assay. This method can
be used to identify compounds, e.g., fragments or analogs of a subject laminin
polypeptide,
which are agonists or antagonists of a subject laminin polypeptide.
In another aspect, the invention features, a method of evaluating a first
compound,

However, we are unsure of the chain associations of y3 within other tissues.
It is very likely
that y3 can also associate with y3, a3, a4, and a5; with (32, ~i3, [34 and

in any of the
methods described herein. E.g., y3 can be assembled with an a and a (3 subunit

laminin trimer.
In any treatment or therapeutic application which administers y3, a (32
subunit can
also be administered.
A "heterologous promoter", as used herein is a promoter which is not naturally
associated with a gene or a purified nucleic acid.
A "purified"or "substantially pure" or isolated "preparation" of a
polypeptide, as used
herein, means a polypeptide that has been separated from other proteins,
lipids, and nucleic
acids with which it naturally occurs. Preferably, the polypeptide is also
separated from
substances, e.g., antibodies or gel matrix, e.g., polyacrylamide, which are
used to purify it.
Preferably, the polypeptide constitutes at least 10, 20, 50 70, 80 or 95% dry
weight of the
purified preparation. Preferably, the preparation contains: sufficient
polypeptide to allow
protein sequencing; at least 1, 10, or 100 ~,g of the polypeptide; at least 1,
10, or 100 mg of
the polypeptide.
A "purified preparation of cells", as used herein, refers to, in the case of
plant or
animal cells, an in vitro preparation of cells and not an entire intact plant
or animal. In the
case of cultured cells or microbial cells, it consists of a preparation of at
least 10% and more
preferably 50% of the subject cells.
A "treatment", as used herein, includes any therapeutic treatment, e.g., the
administration of a therapeutic agent or substance, e.g., a drug.

An "isolated" or " pure nucleic acid", e.g., a substantially pure DNA, is a
nucleic acid
which is one or both of not immediately contiguous with either one or both of
the sequences,
e.g., coding sequences, with which it is immediately contiguous (i.e., one at
the 5' end and
one at the 3' end) in the naturally-occurring genome of the organism from
which the nucleic
acid is derived; or which is substantially free of a nucleic acid sequence
with which it occurs
in the organism from which the nucleic acid is derived. The term includes, for
example, a
recombinant DNA which is incorporated into a vector, e.g., into an
autonomously replicating
plasmid or virus, or into the genomic DNA of a prokaryote or eukaryote, or
which exists as a
separate molecule (e.g., a cDNA or a genomic DNA fragment produced by PCR or
restriction
endonuclease treatment) independent of other DNA sequences. Substantially pure
DNA can
also includes a recombinant DNA which is part of a hybrid gene encoding
sequence.
"Sequence identity or homology", as used herein, refers to the sequence
similarity
between two polypeptide molecules or between two nucleic acid molecules. When
a position
in both of the two compared sequences is occupied by the same base or amino
acid monomer
subunit, e.g., if a position in each of two DNA molecules is occupied by
adenine, then the
molecules are homologous or sequence identical at that position. The percent
of homology or
sequence identity between two sequences is a function of the number of
matching or
homologous identical positions shared by the two sequences divided by the
number of
positions compared x 100. For example, if 6 of 10, of the positions in two
sequences are the
same then the two sequences are 60% homologous or have 60% sequence identity.
By way
of example, the DNA sequences ATTGCC and TATGGC share 50% homology or sequence
identity. Generally, a comparison is made when two sequences are aligned to
give maximum
homology.
The tenors "peptides", "proteins", and "polypeptides" are used interchangeably
herein.
As used herein, the term "transgene" means a nucleic acid sequence {encoding,
e.g.,
one or more subject laminin polypeptides), which is partly or entirely
heterologous, i.e.,
foreign, to the transgenic animal or cell into which it is introduced, or, is
homologous to an
endogenous gene of the transgenic animal or cell into which it is introduced,
but which is
designed to be inserted, or is inserted, into the animal's genome in such a
way as to alter the
genome of the cell into which it is inserted (e.g., it is inserted at a
location which differs from
that of the natural gene or its insertion results in a knockout). A transgene
can include one or
more transcriptional regulatory sequences and any other nucleic acid, such as
introns, that
may be necessary for optimal expression of the selected nucleic acid, all
operably linked to
the selected nucleic acid, and may include an enhancer sequence.
As used herein, the term "transgenic cell" refers to a cell containing a
transgene.
As used herein, a "transgenic animal" is any animal in which one or more, and
preferably essentially all, of the cells of the animal includes a transgene.
The transgene can
be introduced into the cell, directly or indirectly by introduction into a
precursor of the cell,
by way of deliberate genetic manipulation, such as by microinjection or by
infection with a
CA 02304169 2000-03-22
WO 99/19348 PCT/US98/21391
19
recombinant virus. This molecule may be integrated within a chromosome, or it
may be
extrachromosomally replicating DNA. ~ -
As used herein, the term "tissue-specific promoter" means a DNA sequence that
serves as a promoter, i.e., regulates expression of a selected DNA sequence
operably
linked to the promoter, and which effects expression of the selected DNA
sequence in
specific cells of a tissue, such as mammary tissue. The term also covers so-
called "leaky"
promoters, which regulate expression of a selected DNA primarily in one
tissue, but cause
expression in other tissues as well.
"Unrelated to a y3 or (34 amino acid or nucleic acid sequence" means having
less than
30% sequence identity, less than 20% sequence identity, or, preferably, less
than 10%
homology with a naturally occuring y3 or (34 sequence disclosed herein.
A polypeptide has y3 biological activity if it has one or more of the
properties of y3
disclosed herein. A polypeptide has biological activity if it is an
antagonist, agonist, or super-
agonist of a polypeptide having one of the properties of y3 disclosed herein.
A polypeptide has (34 biological activity if it has one or more of the
properties of [34
disclosed herein. A polypeptide has biological activity if it is an
antagonist, agonist, or super-
agonist of a polypeptide having one of the properties of ~i4 disclosed herein.
"Misexpression", as used herein, refers to a non-wild type pattern of gene
expression,
at the RNA or protein level. It includes: expression at non-wild type levels,
i.e., over or under
expression; a pattern of expression that differs from wild type in terms of
the time or stage at
which the gene is expressed, e.g., increased or decreased expression (as
compared with wild
type) at a predetermined developmental period or stage; a pattern of
expression that differs
from wild type in terms of decreased expression (as compared with wild type)
in a
predetermined cell type or tissue type; a pattern of expression that differs
from wild type in
terms of the splicing size, amino acid sequence, post-transitional
modification, or biological
activity of the expressed polypeptide; a pattern of expression that differs
from wild type in
terms of the effect of an environmental stimulus or extracellular stimulus on
expression of the
gene, e.g., a pattern of increased or decreased expression (as compared with
wild type) in the
presence of an increase or decrease in the strength of the stimulus.
Subject, as used herein, can refer to a mammal, e.g., a human, or to an
experimental or
animal or disease model. The subject can also be a non-human animal, e.g., a
horse, cow,
goat, or other domestic animal.
As described herein, one aspect of the invention features a substantially pure
(or
recombinant) nucleic acid which includes a nucleotide sequence encoding a Y3
or ~i4
polypeptide and/or equivalents of such nucleic acids. The term nucleic acid as
used herein
can include fragments and equivalents. The term equivalent refers to
nucleotide sequences
encoding functionally equivalent polypeptides. Equivalent nucleotide sequences
will include
sequences that differ by one or more nucleotide substitutions, additions or
deletions, such as

WO 99/19348 PCT/US98/21391
5 allelic variants, and include sequences that differ from the nucleotide
sequences disclosed
herein by degeneracy of the genetic code.
The practice of the present invention will employ, unless otherwise indicated,
conventional techniques of cell biology, cell culture, molecular biology,
transgenic biology,
microbiology, recombinant DNA, and immunology, which are within the skill of
the art.

Lanvnin 12 was isolated from human placental chorionic villi. Briefly, human
chorionic placental villi were frozen in liquid nitrogen, ground in a Waring
blender and
washed in 1 M NaCI. The final tissue pellet (200g, wet weight) was suspended
in 1 L of
extraction buffer (50 mM Tris-HCl 50 mM, pH=7.8; NaCI O.SM, EDTA IOmM, 625
mg/1 of
N-ethylmaleimide, 150 mg/1 of phenyhnethylsulphonyl fluoride. The suspension
was
incubated at 4°C with stirring for 48 h. Unless otherwise noted, all
subsequent steps were
performed at 4oC. The soluble fraction was collected following centrifugation
(30000 x g, 60
min) and precipitated by 300g11 of Ammonium Sulfate. The precipitated proteins
were
collected by centrifugation (30000 x g, 60 min) and redissolved into
chromatography buffer
(2M Urea, 25 mM NaCI, 5 mM EDTA, and 50 mM Tris-HCI, pH=7.8). The sample was
then
dialyzed against the same buffer. Following dialysis, 0.5 volumes of buffer
equilibrated
DEAE-cellulose (DE-52, Whatman) was added and the mixture shaken overnight.
Material
not bound to DEAF-cellulose was collected by filtration on a Buchner fimnel
(Whatman filter
4) and precipitated by addition of 300g/1 of ammonium sulfate. The proteins
were collected
by centrifugation (30000 x g, 60 min), redissolved in the Concanavalin-A
buffer (0.5 M
NaCI, 5 mM CaCl2, 5 mM MgCl2, and Tris-HCl 50 mM, pH=7.8) and dialyzed against
the
same buffer overnight. The fraction was applied to a 2.5 x 5 cm Concanavalin-A
sepharose
column (Pharmacia), and unbound material was removed by extensive washing.
Bound
proteins were first eluted with 10 mM a-D- Mannopyrannoside (Sigma, St. Louis,
MO) and
secondly with 1 M a-D-Glucopyrannoside (Sigma, St. Louis, MO). A third elution
with 1M
a-D-Manno-pyrannoside (Sigma, St. Louis, MO) allowed the recovery of the
proteins of
interest. Each fraction was independently concentrated to 10 ml on a AmiconT""
concentrator
(30 kDa membrane) and applied to a 2.5 x 100 cm Sephacryl S-500 column in a
0.5 M NaCI,
50 mM Tris-HCI, pH=7.8 buffer. The fractions of interest were pooled, dialyzed
against
Mono-Q buffer (0.1 M NaCI, 25 mM Tris-HCI, pH=7.8) and applied to the 1 x 5 cm
Mono-Q
column (Pharmacia). Elution was achieved with a 60 ml 0.1-0.5 M NaCI gradient.
The final fraction of interest resulting from the above protocol contains
multiple
laminins. The laminin 12 was resolved from this mixture by SDS-PAGE (3-5%
polyacrylamide) under non-reducing conditions. Six band were resolved. Only
the bands at
approximately 560 kDa and at the top of the gel were shown to be reactive with
polyclonal
anti-laminin antiserum (Sigma, St. Louis, MO).
Laminin 12 was excised, equilibrated and reduced in 10°b 2-me SDS-PAGE
sample
buffer, and resolved by 5 % SDS-PAGE. Three bands were resolved, which were
approximately 205 kDa, 185 kDa, and 170 kDa. The band at 185 kDa reacted with
monoclonal antibody 545, specific to the laminin ~i 1 subunit. Each of the
three bands were
CA 02304169 2000-03-22
WO 99/19348 PCT/US98/21391
22
digested with trypsin and the peptides were resolved by HPLC. The selected
resolves were
subject to peptide sequencing.
Protein sequencing was done according to Aebersold et al. (1987). The complex
laminin 5-laminin 7 was run on a polyacrylamide gel in the presence of 2-
mercaptoethanol
and blotted onto a nitrocellulose membrane (Biorad). The 190 kDa band of ~i2
and the
165 kDa a3 band were separately excised and digested by protease trypsin. The
digested
product was separated by HPLC and one fragment was sequenced on an Applied
Biosystems sequenator (Applied Biosystems, Foster City, CA). The 205 kDa chain
contained a sequence identical to human laminin a2, and was thus identified as
human
laminin a2 subunit. The 185 kDa produced two peptides identical to human (31,
and was
thus identified as human laminin ~i 1 subunit. The band at 170 kDa contained
three
sequences not contained in any known laminin chain. A N-terminal sequence of
the 170
kDa chain was also determined. In addition, the N-terminal sequence was not
identical to
any known laminin sequence.
The cDNA sequences of human yl and r2 were used to probe the National Center
for Biomedical Information (NCBI) dBestTM data base by BLAST search and a
clone was
isolated that was homologous, but not identical to yl and y2. This clone was
extended by
PCR at the 5' end using Marathon cDNA from human placenta from Clonetech (Palo
Alto,
CA). The resulting sequence was determined to be 100% identical to all three
of the 170
kDa band peptide sequences.
Comparison of the nucleotide sequence of the isolated y3 subunit to yl,
demonstrated about 80 % sequence identity.
The human cDNA encoding y3, which is approximately 4710 nucleotides in length,
encodes a protein having an estimated molecular weight of approximately 146
kDa (including
post-translational modifications) and which is approximately 1570 amino acid
residues in
length. The human y3 protein contains a nidogen-binding domain, which can be
found, for
example, from about amino acids 750-755 of SEQ ID N0:3. The y3 amino acid
sequence and
the nucleotide sequence encoding human laminin y3 is shown in SEQ ID N0:3 and
SEQ ID
N0:4, respectively.
By Northern analysis the size of the y3 mRNA is approximately 5 kb, which is
consistent with other laminin y subunits. The y3 mRNA transcript is expressed
in human
tissues including spleen, testis, brain, placenta, lung, and possibly liver.
Chromosomal
mapping using the y3 cDNA sequence indicates that the human y3 gene is located
on
CA 02304169 2000-03-22
WO 99/19348 PCT/US98lZ1391
23
chromosome 9q31-34. The location of y3 on chromosome 9 was confirmed by FISH
analysis
using a 1.3 kb y3 cDNA probe within the predicted domains I and II, which
are~the regions of
the least sequence identity among y subunits. Four human genes associated with
Walker-
Walburg syndrome, Fukuyama muscular dystrophy, retinitis pigmentosa-deafness
syndrome
and Eye, Muscle, Brain disease have also been mapped to chromosome 9q31-34.
Production of a y3 specific antibody and tissue lo~~alization of ~
The 170 kDa (y3) chain was excised from the reducing SDS-PAGE gel described
above and inj ected into a rabbit for antibody production. The resulting serum
(rabbit 16) was
evaluated by Western analysis and shown to react with the 170 kDa y3 chain,
and showed
minor crossreactivity with other laminin chains.
Using immunofluorescence, this antiserum shows localization of y3 to the
following
tissue areas: 1) sites of insertions of nerves into the dermal-epidermal
junction basement
membrane of human skin; 2) the inner nuclear layers, outer nuclear layers, and
outer limiting
membranes of human, mouse and rat neural retina; 3) the Purkinje cells, and
molecular
layers, and (perhaps) the glial cells of the mouse and rat cerebellum; 4) the
neuromuscular
junctions of skeletal muscle; and, S) the taste buds of the cow tongue.
The y3 was also shown to colocalize with protein ubiquitin carboxy terminal
hydrolase I using antibody pGp 9.5. The y3 subunit also appears to colocalize
with the a2
subunit in the same tissue sections.
Isolation and Sequencing of cDNA encodLng Q4
The initial 350 by fragment of human laminin (34 cDNA was amplified by
touchdown RT-PCR from cultured human keratinocyte total RNA using nested
primers
made from the published chicken laminin (3 x 503 by cDNA sequence (as
described in Ybot-
Gonzalez et al. (1995)). Subsequent cDNA clones were isolated by nested PCR
directly from
a human placenta cDNA library packaged in lambda-gtl 1 (Clontech, Palo Alto,
CA) or by
nested PCR directly from human placenta Marathon-Ready cDNA (Clontech, Palo
Alto, CA).
The 5' end of the cDNA was cloned using the 5'-RACE technique from human
placenta total
RNA. The Expanded Long Template PCR System (Boehringer Mannheim Biochemicals,
Indianapolis, Il~ was used for all PCR reactions. The PCR products were
ligated into the
pCR2.1 vector (Invitrogen, San Diego, CA) and recombinant plasmids purified
for
sequencing using the QIAprepT"" kit (Qiagen). The DNA sequence was determined
using
either the Sequenase version 2.0 DNA Sequencing Kit (Amersham) and 35S-dATP or
the
Thermo Sequenase Radiolabeled Terminator Cycle Sequencing kit (Amersham) and
33p_
ddNTPs. At least two independent cDNA subclones were sequenced to rule out Taq
polymerase-generated nucleotide substitutions. In some cases, PCR product
bands were
sequenced directly by cycle sequencing after excision from a TAE-EtBr agarose
gel and
purification using QIAquick Gel Extraction kit (Qiagen).

The human cDNA encoding a long form (34, which is approximately 5.87 kb,
encodes
a protein having an estimated molecular weight of approximately 200 kDa and
which is
approximately 1761 amino acid residues in length. The human (34 protein
retains the highest
amino acid sequence identity with domains VI and V, which can be found, for
example, from
about amino acids 221-262 and about 263-535 of SEQ ID NO:1. In addition, a
short form,
splice variant of (34, which is approximately 3.84 kb and an estimated
molecular weight of
120 kDa, was also isolated. The splice variant has 132 nucleotide sequence
identical to the
long form of [34, with the sequence diverging at nucleotide 3375 and spliced
into a unique 3'
I 5 untranslated region. The short form cDNA encodes a truncated (34 subunit
which contains
only the short arm of the (34 subunit and is missing the domains necessary for
heterodimerization. The (34 amino acid sequence and the nucleotide sequence
encoding
human laminin (34 is shown in SEQ ID NO:1 and SEQ ID N0:2, respectively.
Northern analysis was performed using total RNA prepared from JAR cell,
cultured
human keratinocytes and human placenta using either Trizol (Gibco BRL,
Bethesda, MD) or
RNeasyT"" (Qiagen) which was denatured, separated on a formaldehyde agarose
gel and
blotted onto nitrocellulose according to standard protocols (Sambrook, et al.,
1989). In
addition, A human multiple tissue northern blot (Clontech, Palo Alto, CA) and
Human
Northern Terntory normal tissue blots and custom fetal skin northern blot
(Invitrogen, San
Diego, CA) were used. Hybridization and washing were performed using
NorthernMAXT""
buffer system (Ambion) by manufacturer's recommended protocols. 32P-dCTP-
labelled
probes were generated from gel-purified restriction fragments using
RediprimeT"' random
primer labeling kit (Amersham). 32P-UTP-labelled antisense RNA probes were
generated
using the RNA transcription kit (Stratagene, La Jolla, CA) from cDNAs
subcloned into
Bluescript II KS+ (Stratagene, La Jolla, CA).
Northern blotting showed that human laminin ~i4 is expressed in JAR cells,
derived
from undeveloped chronic villi and in placenta. By RT-PCR, it is also
expressed in cultured
keratinocytes. Using a northern blot of human fetal skin developmental
progression, (34
subunit (long form) demonstrates strong expression at week twelve of fetal
development and
persists until birth, but expression is barely detectable in adult skin. The
~i4 splice variant,
however, is expressed in various tissues including adult heart, brain, lung,
liver, skeletal
muscle, kidney, spleen, stomach, esophagus, intestine, colon, uterus, bladder,
adipose tissue
and pancreas. Chromosomal mapping with a (34 cDNA probe indicates that the
human (34
subunit is located at locus 7q22-q31.2. The gene encoding (31 is located near,
but not on, this
position of chromosome 7. Statistical analysis of the mapping data using
markers for ~i 1 and
(34 suggest that the gene encoding ~i 1 is linked to both ends of the gene
encoding ~i4. In
addition, neonatal cutis laxa with manifold phenotype has been mapped near,
but not in the
same position, as the gene encoding (34.

In situ hybridization to wounded human skin grafted into nude mice suggests
that
laminin ~3 x is expressed in the dermis underneath the migrating epidermal
tongues during
wound closure.
A GenBankTM search using the human nucleotide sequence encoding [34 as shown
in
SEQ ID N0:3 revealed an EST, which corresponds to nucleotides 4686-5870 of the
human
10 nucleotide sequence encoding (34 depicted in SEQ ID N0:3. Alignment of cDNA
encoding
~i4 with the genes encoding human laminin X31 and laminin (32 shows 61 % and
59% sequence
identity, respectively, as shown in Figure 5.
Production of a (~4 specific antibodjr and ti ue local'~a ion of j~
15 Antibodies were raised in rabbits against a 26 kDa bacterial fusion protein
which
corresponds to the 175 amino acid residues of domain VI (e.g., from about
amino acid
residues 221-262) of SEQ ID NO:1. Briefly the fusion protein was made by PCR
amplification of nucleotides 302-785 of the cDNA encoding ~i4 using adapter
primers and
cloned in-frame into the NdeI and SacII sites of pET-15b (Novagen). The fusion
protein
20 construct was confirmed by restriction mapping and DNA sequencing.
Expression of the
fusion protein was induced and separated from E. coli proteins using reducing
SDS-PAGE.
Bands corresponding to the fusion protein were excised from the gel,
equilibrated and
homogenized using Freud's adjuvant. The same fusion protein was also western
blotted on
nitrocellulose, dissolved in DMSO and used to immunize mice for monoclonal
antibody
25 production.
The polyclonal antisera raised in mice against the fusion protein reacted well
with (34,
as well as, (31 and (32 polypeptides.
The (34 subunit contains six domains, and a interruption and a signal peptide.
The
signal peptide and domain VI can be found, for example, at about amino acid
residues 1-262
of SEQ ID NO:1. Domain V can be found, for example, at about amino acid
residues 263-
535 of SEQ ID NO:1. Domains IV and III can be found, for example, at about
amino acid
residues 536-767 and 768-1178 of SEQ ID NO:1, respectively. Domain I can be
found, for
example, at about amino acid residues 1409-1761 of SEQ ID NO:I.
The (34 suburut (long form) is most similar in size and domain structure to
laminin (31
with an amino acid sequence identity of 42.5%. (34 retains the highest levels
of amino acid
identity with the other laminin ~3 subunits in domains VI and V, and the
lowest levels in
domains I and II, as shown in Figure 6. Using the MulticoilT"" program, it was
determined
that only domains I and II of (34 have a high probability of forming coiled
coil structures.
Domains I and II of ~i4 look most similar to human (33. Both [34 and (i3 are
epithelial and the
coiled coil structures in domains I and II dictate the a and y subunits with
which the ~i
CA 02304169 2000-03-22
WO 99/19348 PGT/US98/21391
26
subunits are associated. Thus, it is likely that /34 associates with a3 and
y2, as does the
laminin (33 subunit.
The cDNA encoding the splice variant of ~i4 contains only the short arm of the
(34
subunit, and is missing the EGF repeat of domain III, as shown in Figure 5.
Thus, the (34
polypeptide encoded by the [34 c DNA splice variant is missing the coiled coil
structures in
domains I and II, rendering the short subunit unable to associate into a
laminin heterotrimer.
PCR amplification of human genomic DNA suggest that the exon which encodes the
alternative short form 3' untranslated region is located downstream from the
carboxyl-most
common exon, exon 23, and is splices out of the (34 subunit, long form, by
exon skipping.
Analogs o~r3 and ~
Analogs can differ from naturally occurring y3 or [34 in amino acid sequence
or in
ways that do not involve sequence, or both. Non-sequence modifications include
in vivo or
in vitro chemical derivatization of y3 or ~i4. Non-sequence modifications
include changes in
acetylation, methylation, phosphorylation, carboxylation, or glycosylation.
Preferred analogs include y3 or (34 (or biologically active fiagments thereof)
whose
sequences differ from the wild-type sequence by one or more conservative amino
acid
substitutions or by one or more non-conservative amino acid substitutions,
deletions, or
insertions which do not abolish the Y3 or (34 biological activity.
Conservative substitutions
typically include the substitution of one amino acid for another with similar
characteristics,
e.g., substitutions within the following groups: valine, glycine; glycine,
alanine; valine,
isoleucine, leucine; aspartic acid, glutamic acid; asparagine, glutamine;
serine, threonine;
lysine, arginine; and phenylalanine, tyrosine. Other conservative
substitutions can be taken
from the table below.

The gene constructs of the invention can also be used as a part of a gene
therapy
protocol to deliver nucleic acids encoding either an agonistic or antagonistic
form of a Y3 ar (3
4 polypeptide. The invention features expression vectors for in vivo
transfection and
expression of a y3 or ~i4 polypeptide in particular cell types so as to
reconstitute the function
of, or alternatively, antagonize the function of y3 or (i4 polypeptide in a
cell in which that
polypeptide is misexpressed. Expression constructs of y3 or (34 polypeptides,
may be
administered in any biologically effective carrier, e.g. any formulation or
composition
capable of effectively delivering the Y3 or ~i4 gene to cells in vivo.
Approaches include
insertion of the subject gene in viral vectors including recombinant
retroviruses, adenovirus,
adeno-associated virus, and herpes simplex virus-l, or recombinant bacterial
or eukaryotic
plasmids. Viral vectors transfect cells directly; plasmid DNA can be delivered
with the help
of, for example, cationic liposomes (lipofectin) or derivatized (e.g. antibody
conjugated),
polylysine conjugates, gramacidin S, artificial viral envelopes or other such
intracellular
carriers, as well as direct injection of the gene construct or CaP04
precipitation carried out in
vivo.
A preferred approach for in vivo introduction of nucleic acid into a cell is
by use of a
viral vector containing nucleic acid, e.g. a cDNA, encoding a y3 or (34
polypeptide. Infection
of cells with a viral vector has the advantage that a large proportion of the
targeted cells can
receive the nucleic acid. Additionally, molecules encoded within the viral
vector, e.g., by a
cDNA contained in the viral vector, are expressed efficiently in cells which
have taken up
viral vector nucleic acid.
Retrovirus vectors and adeno-associated virus vectors can be used as a
recombinant
gene delivery system for the transfer of exogenous genes in vivo, particularly
into humans.
These vectors provide efficient delivery of genes into cells, and the
transferred nucleic acids
are stably integrated into the chromosomal DNA of the host. The development of
specialized
cell lines (termed "packaging cells") which produce only replication-defective
retroviruses
has increased the utility of retroviruses for gene therapy, and defective
retroviruses are
characterized for use in gene transfer for gene therapy purposes (for a review
see Miller, A.D.
( 1990) Blood 76:271 ). A replication defective retrovirus can be packaged
into virions which
can be used to infect a target cell through the use of a helper virus by
standard techniques.
Protocols for producing recombinant retroviruses and for infecting cells in
vitro or in vivo
with such viruses can be found in Cu_r_rent Protocols in Molecul r ioloev,
Ausubel, F.M. et
aI. (eds.) Greene Publishing Associates, (1989), Sections 9.10-9.14 and other
standard
laboratory manuals. Examples of suitable retroviruses include pLJ, pZIP, pWE
and pEM
which are known to those skilled in the art. Examples of suitable packaging
virus lines for

Another viral gene delivery system useful in the present invention utilizes
adenovirus-
derived vectors. The genome of an adenovirus can be manipulated such that it
encodes and
expresses a gene product of interest but is inactivated in terms of its
ability to replicate in a
normal lytic viral life cycle. See, for example, Berkner et al. (1988)
BioTechnigues 6:616;
Rosenfeld et al. (1991) Science 252:431-434; and Rosenfeld et al. (1992) Cell
68:143-155.
Suitable adenoviral vectors derived from the adenovirus strain Ad type 5 d1324
or other
strains of adenovirus (e.g., Ad2, Ad3, Ad7 etc.) are known to those skilled in
the art.
Recombinant adenoviruses can be advantageous in certain circumstances in that
they are not
capable of infecting nondividing cells and can be used to infect a wide
variety of cell types,
including epithelial cells (Rosenfeld et al. (1992) cited supra). Furthermore,
the virus particle
is relatively stable and amenable to purification and concentration, and as
above, can be
modified so as to affect the spectrum of infectivity. Additionally, introduced
adenoviral
DNA (and foreign DNA contained therein) is not integrated into the genome of a
host cell but
remains episomal, thereby avoiding potential problems that can occur as a
result of insertional
mutagenesis in situations where introduced DNA becomes integrated into the
host genome
(e.g., retroviral DNA). Moreover, the carrying capacity of the adenoviral
genome for foreign
DNA is large (up to 8 kilobases) relative to other gene delivery vectors
(Berkner et al. cited
supra; Haj-Ahmand and Graham (1986) J. Virol. 57:267).
Yet another viral vector system useful for delivery of the subject gene is the
adeno-
associated virus (AAV). Adeno-associated virus is a naturally occurring
defective virus that
requires another virus, such as an adenovirus or a herpes virus, as a helper
virus for efficient
replication and a productive life cycle. (For a review see Muzyczka et al.
Curr. Topics in
Micro. and Immunol. (1992) 158:97-129). It is also one of the few viruses that
may integrate
its DNA into non-dividing cells, and exhibits a high frequency of stable
integration (see for
example Flotte et al. (1992) Am. J. Respir. Cell. Mol. Biol. 7:349-356;
Samulski et al. (1989)
J. Virol. 63:3822-3828; and McLaughlin et al. (1989) J. Virol. 62:1963-1973).
Vectors
containing as little as 300 base pairs of AAV can be packaged and can
integrate. Space for
exogenous DNA is limited to about 4.5 kb. An AAV vector such as that described
in
Tratschin et al. (1985) Mol. Cell. Biol. 5:3251-3260 can be used to introduce
DNA into cells.
A variety of nucleic acids have been introduced into different cell types
using AAV vectors

In addition to viral transfer methods, such as those illustrated above, non-
viral
10 methods can also be employed to cause expression of a y3 or (34 polypeptide
in the tissue of
an animal. Most nonviral methods of gene transfer rely on normal mechanisms
used by
mammalian cells for the uptake and intracellular transport of macromolecules.
In preferred
embodiments, non-viral gene delivery systems of the present invention rely on
endocytic
pathways for the uptake of the subject y3 or ~i4 gene by the targeted cell.
Exemplary gene
15 delivery systems of this type include liposomal derived systems, poly-
lysine conjugates, and
artificial viral envelopes.
In a representative embodiment, a gene encoding a y3 or (34 polypeptide can be
entrapped in liposomes bearing positive charges on their surface (e.g.,
lipofectins) and
(optionally) which are tagged with antibodies against cell surface antigens of
the target tissue
20 (Mizuno et al. (1992) No Shinkei Geka 20:547-551; PCT publication
W091/06309;
Japanese patent application 1047381; and European patent publication EP-A-
43075).
In clinical settings, the gene delivery systems for the therapeutic y3 or ~i4
gene can be
introduced into a patient by any of a number of methods, each of which is
familiar in the art.
For instance, a pharmaceutical preparation of the gene delivery system can be
introduced
25 systemically, e.g. by intravenous injection, and specific transduction of
the protein in the
target cells occurs predominantly from specificity of transfection provided by
the gene
delivery vehicle, cell-type or tissue-type expression due to the
transcriptional regulatory
sequences controlling expression of the receptor gene, or a combination
thereof. In other
embodiments, initial delivery of the recombinant gene is more limited with
introduction into
30 the animal being quite localized. For example, the gene delivery vehicle
can be introduced by
catheter (see U.S. Patent 5,328,470) or by Stereotactic injection (e.g. Chen
et al. (1994) PNAS
91: 3054-3057).
The pharmaceutical preparation of the gene therapy construct can consist
essentially
of the gene delivery system in an acceptable diluent, or can comprise a slow
release matrix in
which the gene delivery vehicle is imbedded. Alternatively, where the complete
gene
delivery system can be produced in tact from recombinant cells, e.g.
retroviral vectors, the
pharmaceutical preparation can comprise one or more cells which produce the
gene delivery
system.
Transgenic nimal_s
The invention includes transgenic animals which include cells (of that animal)
which contain a y3 or (34 transgene and which preferably (though optionally)
express (or
misexpress) an endogenous or exogenous y3 or ~i4 gene in one or more cells in
the animal.
CA 02304169 2000-03-22
WO 99/19348 PCT/US98/21391
31
The y3 or (34 transgene can encode the wild-type form of the protein, or can
encode homologs
thereof, including both agonists and antagonists, as well as antisense
constructs: In preferred
embodiments, the expression of the transgene is restricted to specific subsets
of cells, or
tissues utilizing, for example, cis-acting sequences that control expression
in the desired
pattern. Tissue-specific regulatory sequences and conditional regulatory
sequences can be
used to control expression of the transgene in certain spatial patterns, e.g.,
to restrict
production to the milk or other secreted product of the animal.
Fragments of a protein can be produced in several ways, e.g., recombinantly,
by
proteolytic digestion, or by chemical synthesis. Internal or terminal
fragments of a
polypeptide can be generated by removing one or more nucleotides from one end
(for a
terminal fragment) or both ends (for an internal fragment) of a nucleic acid
which encodes the
polypeptide. Expression of the mutagenized DNA produces polypeptide fragments.
Digestion with "end-nibbling" endonucleases can thus generate DNA's which
encode an array
of fragments. DNA's which encode fragments of a protein can also be generated
by random
shearing, restriction digestion or a combination of the above-discussed
methods.
Fragments can also be chemically synthesized using techniques known in the art
such
as conventional Merrifield solid phase f Moc or t-Boc chemistry. For example,
peptides of
the present invention may be arbitrarily divided into fragments of desired
length with no
overlap of the fragments, or divided into overlapping fragments of a desired
length.
Amino acid sequence variants of a protein can be prepared by random
mutagenesis of
DNA which encodes a protein or a particular domain or region of a protein.
Useful methods
include PCR mutagenesis and saturation mutagenesis. A library of random amino
acid
sequence variants can also be generated by the synthesis of a set of
degenerate
oligonucleotide sequences. (Methods for screening proteins in a library of
variants are
elsewhere herein.)
PCR Mutagenesis
In PCR mutagenesis, reduced Taq polymerise fidelity is used to introduce
random
mutations into a cloned fragment of DNA (Leung et al., 1989, Technique 1:11-
15). This is a
very powerful and relatively rapid method of introducing random mutations. The
DNA
region to be mutagenized is amplified using the polymerise chain reaction
(PCR) under
conditions that reduce the fidelity of DNA synthesis by Taq DNA polymerise,
e.g., by using
a dGTP/dATP ratio of five and adding Mn2+ to the PCR reaction. The pool of
amplified
CA 02304169 2000-03-22
WO 99/19348 PCT/US981Z1391
32
DNA fragments are inserted into appropriate cloning vectors to provide random
mutant
libraries.
Saturation Mutagenesis
Saturation mutagenesis allows for the rapid introduction of a large number of
single
base substitutions into cloned DNA fragments (Mayers et al., 1985, Science
229:242). This
technique includes generation of mutations, e.g., by chemical treatment or
irradiation of
single-stranded DNA in vitro, and synthesis of a complimentary DNA strand. The
mutation
frequency can be modulated by modulating the severity of the treatment, and
essentially all
possible base substitutions can be obtained. Because this procedure does not
involve a
genetic selection for mutant fragments both neutral substitutions, as well as
those that alter
function, are obtained. The distribution of point mutations is not biased
toward conserved
sequence elements.
Degenerate Oligonucleotides
A library of homologs can also be generated from a set of degenerate
oligonucleotide
sequences. Chemical synthesis of a degenerate sequences can be carried out in
an automatic
DNA synthesizer, and the synthetic genes then ligated into an appropriate
expression vector.
The synthesis of degenerate oligonucleotides is known in the art (see for
example, Narang,
SA (1983) Tetrahedron 39:3; Itakura et al. (1981) Recombinant DNA, Proc 3rd
Cleveland

et al.

et al. (1983)
Nucleic Acid Res. 11:477. Such techniques have been employed in the directed
evolution of
other proteins (see, for example, Scott et al. (1990) Science 249:386-390;
Roberts et al.
(1992) PNAS 89:2429-2433; Devlin et al. (1990) Science 249: 404-406; Cwirla et
al. (1990)
PNAS 87: 6378-6382; as well as U.S. Patents Nos. 5,223,409, 5,198,346, and
5,096,815).
Non-random or directed, mutagenesis techniques can be used to provide specific
sequences or mutations in specific regions. These techniques can be used to
create variants
which include, e.g., deletions, insertions, or substitutions, of residues of
the known amino
acid sequence of a protein. The sites for mutation can be modified
individually or in series,
e.g., by (1) substituting first with conserved amino acids and then with more
radical choices
depending upon results achieved, (2) deleting the target residue, or (3)
inserting residues of
the same or a different class adjacent to the located site, or combinations of
options 1-3.
Alanine Scanning Mutagenesis
CA 02304169 2000-03-22
WO 99/19348 PCT/US98/21391
33
S Alanine scanning mutagenesis is a useful method for identification of
certain residues
or regions of the desired protein that are preferred locations or domains for
mutagenesis,-
Cunningham and Wells (Science 244:1081-1085, 1989}. In alanine scanning, a
residue or
group of target residues are identified (e.g., charged residues such as Arg,
Asp, His, Lys, and
Glu) and replaced by a neutral or negatively charged amino acid (most
preferably alanine or
polyalanine). Replacement of an amino acid can affect the interaction of the
amino acids
with the surrounding aqueous environment in or outside the cell. Those domains
demonstrating functional sensitivity to the substitutions are then refined by
introducing
further or other variants at or for the sites of substitution. Thus, while the
site for introducing
an amino acid sequence variation is predetermined, the nature of the mutation
per se need not
be predetermined. For example, to optimize the performance of a mutation at a
given site,
alanine scanning or random mutagenesis may be conducted at the target codon or
region and
the expressed desired protein subunit variants are screened for the optimal
combination of
desired activity.
Oligonucleotide-Mediated Mutagenesis
Oligonucleotide-mediated mutagenesis is a useful method for preparing
substitution,
deletion, and insertion variants of DNA, see, e.g., Adehnan et al., (DNA
2:183, 1983).
Briefly, the desired DNA is altered by hybridizing an oligonucleotide encoding
a mutation to
a DNA template, where the template is the single-stranded form of a plasmid or
bacteriophage containing the unaltered or native DNA sequence of the desired
protein. After
hybridization, a DNA polymerase is used to synthesize an entire second
complementary
strand of the template that will thus incorporate the oligonucleotide primer,
and will code for
the selected alteration in the desired protein DNA. Generally,
oligonucleotides of at least 25
nucleotides in length are used. An optimal oligonucleotide will have 12 to 15
nucleotides
that are completely complementary to the template on either side of the
nucleotides) coding
for the mutation. This ensures that the oligonucleotide will hybridize
properly to the single-
stranded DNA template molecule. The oligonucleotides are readily synthesized
using
techniques known in the art such as that described by Crea et al. (Proc. Natl.
Acad. Sci. USA,
75: 5765[1978]).
Cassette Mutagenesis
Another method for preparing variants, cassette mutagenesis, is based on the
technique described by Wells et al. (Gene, 34:315[1985]). The starting
material is a plasmid
(or other vector) which includes the protein subunit DNA to be mutated. The
codon(s) in the
protein subunit DNA to be mutated are identified. There must be a unique
restriction
endonuclease site on each side of the identified mutation site(s). If no such
restriction sites
exist, they may be generated using the above-described oligonucleotide-
mediated
mutagenesis method to introduce them at appropriate locations in the desired
protein subunit

WO 99/19348 PCT/US98/21391
34
DNA. After the restriction sites have been introduced into the plasmid, the
plasmid is cut at
these sites to linearize it. A double-stranded oligonucleotide encoding the
sequence of the
DNA between the restriction sites but containing the desired mutations) is
synthesized using
standard procedures. The two strands are synthesized separately and then
hybridized together
using standard techniques. This double-stranded oligonucleotide is referred to
as the cassette.
This cassette is designed to have 3' and 5' ends that are comparable with the
ends of the
linearized plasmid, such that it can be directly ligated to the plasmid. This
plasmid now
contains the mutated desired protein subunit DNA sequence.
Combinatorial Mutagenesis
Combinatorial mutagenesis can also be used to generate mutants. E.g., the
amino acid
sequences for a group of homologs or other related proteins are aligned,
preferably to
promote the highest homology possible. All of the amino acids which appear at
a given
position of the aligned sequences can be selected to create a degenerate set
of combinatorial
sequences. The variegated library of variants is generated by combinatorial
mutagenesis at
the nucleic acid level, and is encoded by a variegated gene library. For
example, a mixture of
synthetic oligonucleotides can be enzymatically ligated into gene sequences
such that the
degenerate set of potential sequences are expressible as individual peptides,
or alternatively,
as a set of larger fusion proteins containing the set of degenerate sequences.

Various techniques are known in the art for screening generated mutant gene
products.
Techniques for screening large gene libraries often include cloning the gene
library into
replicable expression vectors, transforming appropriate cells with the
resulting library of
vectors, and expressing the genes under conditions in which detection of a
desired activity,
e.g., in this case, binding to other laminin subunits, assembly into a
trimeric laminin
molecules, binding to natural ligands or substrates, facilitates relatively
easy isolation of the
vector encoding the gene whose product was detected. Each of the techniques
described
below is amenable to high through-put analysis for screening large numbers of
sequences
created, e.g., by random mutagenesis techniques.
Two Hybrid Systems
Two hybrid assays such as the system described above (as with the other
screening
methods described herein), can be used to identify fragments or analogs. These
may include
agonists, superagonists, and antagonists. (The subject protein and a protein
it interacts with
are used as the bait protein and fish proteins.) .
Display Libraries
CA 02304169 2000-03-22
WO 99/19348 PCTNS98/Z1391
5 In one approach to screening assays, the candidate peptides are displayed on
the
surface of a cell or viral particle, and the ability of particular cells or
viral particles to bind an
appropriate receptor protein via the displayed product is detected in a
"panning assay". For
example, the gene library can be cloned into the gene for a surface membrane
protein of a
bacterial cell, and the resulting fusion protein detected by panning (Ladner
et al., WO
10 88/06630; Fuchs et al. (1991) BiolTechnology 9:1370-1371; and Goward et al.
(1992) TIBS
18:136-140). In a similar fashion, a detectably labeled ligand can be used to
score for
potentially functional peptide homologs. Fluorescently labeled ligands, e.g.,
receptors, can be
used to detect homolog which retain ligand-binding activity. The use of
fluorescently labeled
ligands, allows cells to be visually inspected and separated under a
fluorescence microscope,
15 or, where the morphology of the cell permits, to be separated by a
fluorescence-activated cell
sorter.
A gene library can be expressed as a fusion protein on the surface of a viral
particle.
For instance, in the filamentous phage system, foreign peptide sequences can
be expressed on
the surface of infectious phage, thereby conferring two significant benefits.
First, since these
20 phage can be applied to affinity matrices at concentrations well over 1013
phage per milliliter,
a large number of phage can be screened at one time. Second, since each
infectious phage
displays a gene product on its surface, if a particular phage is recovered
from an affinity
matrix in low yield, the phage can be amplified by another round of infection.
The group of
almost identical E. coli filamentous phages M13, fd., and fl are most often
used in phage
25 display libraries. Either of the phage gIII or gVIII coat proteins can be
used to generate
fusion proteins without disrupting the ultimate packaging of the viral
particle. Foreign
epitopes can be expressed at the NH2-terminal end of pIII and phage bearing
such epitopes
recovered from a large excess of phage lacking this epitope (Ladner et al. PCT
publication
WO 90/02909; Garrard et al., PCT publication WO 92/09690; Marks et al. (1992)
J. Biol.
30 Chem. 267:16007-16010; Griffiths et al. (1993} EMBO J 12:725-734; Clackson
et al. (1991)
Nature 352:624-628; and Barbas et al. (1992) PNAS 89:4457-4461).
A common approach uses the maltose receptor of E. coli (the outer membrane
protein,
Lama) as a peptide fusion partner (Charbit et al. (1986) EMBO 5, 3029-3037).
Oligonucleotides have been inserted into plasmids encoding the Lama gene to
produce
35 peptides fused into one of the extracellular loops of the protein. These
peptides are available
for binding to ligands, e.g., to antibodies, and can elicit an immune response
when the cells
are administered to animals. Other cell surface proteins, e.g., OmpA (Schorr
et al. (1991)
Vaccines 91, pp. 387-392), PhoE (Agterberg, et al. {1990) Gene 88, 37-45}, and
PAL (Fuchs
et al. (1991) BiolTech 9, 1369-1372), as well as large bacterial surface
structures have served
as vehicles for peptide display. Peptides can be fused to pilin, a protein
which polymerizes to
form the pilus-a conduit for interbacterial exchange of genetic information
(Thiry et al.
(1989) Appl. Environ. Microbiol. 55, 984-993). Because of its role in
interacting with other
cells, the pilus provides a useful support for the presentation of peptides to
the extracellular
CA 02304169 2000-03-22
WO 99/19348 PCT/US98/21391
36
environment. Another large surface structure used for peptide display is the
bacterial motive
organ, the flagellum. Fusion of peptides to the subunit protein flagellin
offers a dense array
of may peptides copies on the host cells (Kuwajima et al. (1988) BiolTech. 6,
1080-1083).
Surface proteins of other bacterial species have also served as peptide fusion
partners.
Examples include the Staphylococcus protein A and the outer membrane protease
IgA of
Neisseria (Hansson et al. (1992) J. Bacteriol. 174, 4239-4245 and Klauser et
al. (1990)
EMBO J. 9, 1991-1999}.
In the filamentous phage systems and the Lama system described above, the
physical
link between the peptide and its encoding DNA occurs by the containment of the
DNA within
a particle (cell or phage) that carries the peptide on its surface. Capturing
the peptide captures
the particle and the DNA within. An alternative scheme uses the DNA-binding
protein LacI
to form a link between peptide and DNA (Cull et al. (1992) PNAS USA 89:1865-
1869). This
system uses a plasmid containing the LacI gene with an oligonucleotide cloning
site at its 3'-
end. Under the controlled induction by arabinose, a LacI-peptide fusion
protein is produced.
This fusion retains the natural ability of LacI to bind to a short DNA
sequence known as
LacO operator (LacO). By installing two copies of LacO on the expression
plasmid, the
LacI-peptide fusion binds tightly to the plasmid that encoded it. Because the
plasmids in
each cell contain only a single oligonucleotide sequence and each cell
expresses only a single
peptide sequence, the peptides become specifically and stably associated with
the DNA
sequence that directed its synthesis. The cells of the library are gently
lysed and the peptide-
DNA complexes are exposed to a matrix of immobilized receptor to recover the
complexes
containing active peptides. The associated plasmid DNA is then reintroduced
into cells for
amplification and DNA sequencing to determine the identity of the peptide
ligands. As a
demonstration of the practical utility of the method, a large random library
of dodecapeptides
was made and selected on a monoclonal antibody raised against the opioid
peptide dynorphin
B. A cohort of peptides was recovered, all related by a consensus sequence
corresponding to
a six-residue portion of dynorphin B. (Cull et al. (1992) Proc. Natl. Aced.
Sci. U.S.A. 89-
1869)
This scheme, sometimes referred to as peptides-on-plasmids, differs in two
important
ways from the phage display methods. First, the peptides are attached to the C-
terminus of
the fusion protein, resulting in the display of the library members as
peptides having free
carboxy termini. Both of the filamentous phage coat proteins, pIII and pVIII,
are anchored to
the phage through their C-termini, and the guest peptides are placed into the
outward-
extending N-terminal domains. In some designs, the phage-displayed peptides
are presented
right at the amino terminus of the fusion protein. (Cwirla, et al. (1990)
Proc. Natl. Aced. Sci.
U.S A. 87, 6378-6382) A second difference is the set of biological biases
affecting the
population of peptides actually present in the libraries. The LacI fusion
molecules are
confined to the cytoplasm of the host cells. The phage coat fusions are
exposed briefly to the
cytoplasm during translation but are rapidly secreted through the inner
membrane into the
CA 02304169 2000-03-22
WO 99/19348 PGT/US98/21391
37
periplasmic compartment, remaining anchored in the membrane by their C-
terminal
hydrophobic domains, with the N-termini, containing the peptides, protruding
into the
periplasm while awaiting assembly into phage particles. The peptides in the
LacI and phage
libraries may differ significantly as a result of their exposure to different
proteoLytic activities.
The phage coat proteins require transport across the inner membrane and signal
peptidase
processing as a prelude to incorporation into phage. Certain peptides exert a
deleterious
effect on these processes and are underrepresented in the libraries (Gallop et
al. (1994) J.
Med. Chem. 37(9):1233-1251). These particular biases are not a factor in the
LacI display
system.
The number of small peptides available in recombinant random libraries is
enormous.
Libraries of 10~-109 independent clones are routinely prepared. Libraries as
large as 1011
recombinants have been created, but this size approaches the practical limit
for clone
libraries. This limitation in Library size occurs at the step of transforming
the DNA
containing randomized segments into the host bacterial cells. To circumvent
this limitation,
an in vitro system based on the display of nascent peptides in polysome
complexes has
recently been developed. This display library method has the potential of
producing libraries
3-6 orders of magnitude larger than the currently available phage/phagemid or
plasmid
Libraries. Furthermore, the construction of the libraries, expression of the
peptides, and
screening, is done in an entirely cell-free format.
In one application of this method (Gallop et a1. (1994) J. Med Chem.
37(9):1233-
1251 ), a molecular DNA library encoding 1012 decapeptides was constructed and
the library
expressed in an E. coli S30 in vitro coupled transcription/translation system.
Conditions were
chosen to stall the ribosomes on the mRNA, causing the accumulation of a
substantial
proportion of the RNA in polysomes and yielding complexes containing nascent
peptides still
linked to their encoding RNA. The polysomes are sufficiently robust to be
affinity purified
on immobilized receptors in much the same way as the more conventional
recombinant
peptide display Libraries are screened. RNA from the bound complexes is
recovered,
converted to cDNA, and amplified by PCR to produce a template for the next
round of
synthesis and screening. The polysome display method can be coupled to the
phage display
system. Following several rounds of screening, cDNA from the enriched pool of
polysomes
was cloned into a phagemid vector. This vector serves as both a peptide
expression vector,
displaying peptides fused to the coat proteins, and as a DNA sequencing vector
for peptide
identification. By expressing the polysome-derived peptides on phage, one can
either
continue the affinity selection procedure in this format or assay the peptides
on individual
clones for binding activity in a phage ELISA, or for binding specificity in a
completion phage
ELISA (Barnet, et al. (1992) Anal. Biochem 204,357-364). To identify the
sequences of the
active peptides one sequences the DNA produced by the phagemid host.

The high through-put assays described above can be followed by secondary
screens in
order to identify further biological activities which will, e.g., allow one
skilled in the art-to
differentiate agonists from antagonists. The type of a secondary screen used
will depend on
the desired activity that needs to be tested. For example, an assay can be
developed in which
the ability to inhibit an interaction between a protein of interest and its
respective ligand can
be used to identify antagonists from a group of peptide fragments isolated
though one of the
primary screens described above.
Therefore, methods for generating fragments and analogs and testing them for
activity
are known in the art. Once the core sequence of interest is identified, it is
routine to perform
for one skilled in the art to obtain analogs and fragments.
P~ntide Mimetics
The invention also provides for reduction of the protein binding domains of
the
subject y3 or (34 polypeptides to generate mimetics, e.g. peptide or non-
peptide agents. See,
for example, "Peptide inhibitors of human papillomavirus protein binding to
retinoblastoma
gene protein" European patent applications EP-412,762A and EP-B31,080A.
Non-hydrolyzable peptide analogs of critical residues can be generated using
benzodiazepine (e.g., see Freidinger et al. in Peptides: Chemistry and
Biology, G.R. Marshall
ed., ESCOM Publisher: Leiden, Netherlands, 1988), azepine (e.g., see Huffinan
et al. in
Peptides: Chemistry and Biology, G.R. Marshall ed., ESCOM Publisher: Leiden,
Netherlands, 1988), substituted gama lactam rings (Garvey et al. in Peptides:
Chemistry and
Biology, G.R. Marshall ed., ESCOM Publisher: Leiden, Netherlands, 1988), keto-
methylene
pseudopeptides (Ewenson et al. (1986) JMed Chem 29:295; and Ewenson et al. in
Peptides:
Structure and Function (Proceedings of the 9th American Peptide Symposium)
Pierce
Chemical Co. Rockland, IL, 1985), (3-turn dipeptide cores (Nagai et al. (1985)
Tetrahedron
Lett 26:647; and Sato et al. ( 1986) J Chem Soc Perkin Trans 1:1231 ), and (3-
aminoalcohols
(Gordon et al. (1985) Biochem Biophys Res Commun126:419; and Dann et al.
(1986)
Biochem Biophys Res Commun 134:71).
~~ntibodies
The invention also includes antibodies specifically reactive with a subject y3
or (34
polypeptides. Anti-protein/anti-peptide antisera or monoclonal antibodies can
be made by
standard protocols (See, for example, Antibodies: A Laboratory Manual ed. by
Harlow and
Lane (Cold Spring Harbor Press: 1988)).
Antibodies which specifically bind y3 or (34 epitopes can also be used in
immunohistochemical staining of tissue samples in order to evaluate the
abundance and
pattern of expression of y3 or [34. Anti y3 or (34 antibodies can be used
diagnostically in

WO 99/19348 PCT/US98/21391
39
S immuno-precipitation and immuno-blotting to detect and evaluate y3 or ~i4
levels in tissue or
bodily fluid as part of a clinical testing procedure.
Another application of antibodies of the present invention is in the
immunological
screening of cDNA libraries constructed in expression vectors such as ~,gtl l,
~.gtl8-23,
7v.ZAP, and ~,ORF8. Messenger libraries of this type, having coding sequences
inserted in the
correct reading frame and orientation, can produce fusion proteins. For
instance, ~,gtl l will
produce fusion proteins whose amino termini consist of 13-galactosidase amino
acid sequences
and whose carboxy tenmini consist of a foreign polypeptide. Antigenic epitopes
of a subject
polypeptide can then be detected with antibodies, as, for example, reacting
nitrocellulose
filters lifted from infected plates with antibodies of the invention. Phage,
scored by this
assay, can then be isolated from the infected plate. Thus, the presence of
homologs can be
detected and cloned from other animals, and alternate isoforms (including
splicing variants)
can be detected and cloned from human sources.
Other Embodiments
Included in the invention are: allelic variations; natural mutants; induced
mutants;
proteins encoded by DNA that hybridizes under high or low stringency
conditions to a
nucleic acid which encodes a polypeptide of SEQ ID NO:1 or SEQ ID N0:3 (for
definitions
of high and low stringency see Current Protocols in Molecular Biology, John
Wiley & Sons,
New York, 1989, 6.3.1 - 6.3.6, hereby incorporated by reference); and,
polypeptides
specifically bound by antisera to Y3 or ~i4.
Nucleic acids and polypeptides of the invention includes those that differ
from the
sequences discolosed herein by virtue of sequencing errors in the disclosed
sequences.
The invention also includes fragments, preferably biologically active
fragments, or
analogs of y3 or ~i4. A biologically active fragment or analog is one having
any in vivo or in
vitro activity which is characteristic of they3 or (34 shown in SEQ ID N0:3
and SEQ ID
NO:1, respectively, or of other naturally occurring y3 or (34, e.g., one or
more of the
biological activities described above. Especially preferred are fragments
which exist in vivo,
e.g., fragments which arise from post transcriptional processing or which
arise from
translation of alternatively spliced RNA's. Fragments include those expressed
in native or
endogenous cells, e.g., as a result of post-translational processing, e.g., as
the result of the
removal of an amino-terminal signal sequence, as well as those made in
expression systems,
e.g., in CHO cells. Particularly preferred fragments are fragments, e.g.,
active fragments,
which are generated by proteolytic cleavage or alternative splicing events.
