CONTRACEPTIVE VACCINE

Abstract: The subject disclosure relates to methods of contraception, and compositions useful in such methods. Disclosed are methods in which one or more sperm surface proteins are administered to a mammal, the administration being effective in stimulating an immune response whereby antibody which binds to the sperm surface protein is produced in a titer sufficient to prevent or substantially reduce the rate of sperm-egg fusion. Antigenic sperm surface protein peptides are also useful for this purpose.

Description: CONTRACEPTIVE VACCINE Background Immunization of male and female animals with extracts of whole sperm cells is known to cause infertility (Tung, K. , et al.. J. of Reproductive Immunol.. 1 ' 145-158 (1979) and Menge, A., et al.. Biol. of Reproduction. 20: 931-937 (1979)). Also, men and women who spontaneously produce antisperm antibodies are infertile, but otherwise healthy (Bronson, R. et al.. Fert. and Steril.. 42; 171-183 (1984)). Although the critical sperm antigens are unknown, these observations have led to the proposal that sperm proteins might be useful in the development of a contraceptive vaccine. In mammalian species, sperm proteins have been proposed to have a role in sperm adhesion to the zona pellucida of the egg. In the mouse, it has been shown that a sperm surface galactosyl transferase is an adhesion protein that functions in acrosome-intact sperm binding to the zona (Shur, B.E., Galactosyl transferase as a recognition molecule durinσ fertilization and development. In: "The Molecular Biology of Fertilization," Eds. Schatten, H. , and Schatten, G., Academic Press, pps. 37-71 (1989)). On rat sperm, there is a galactose receptor, (RTG-r) , related to the hepatic asialoglycoprotein receptor, which could function through its lectin properties in sperm binding to zona oligosaccharides (Abdullah, M. , and Kierszenbaum, A.L., J. Cell Biol.. 108: 367-375 (1989)). A boar sperm plasma membrane protein (AP 2 ) , distinct from galactosyl transferase, and a rabbit sperm protein have also been reported to have a role in sperm-zona adhesion (Peterson, R.N. and Hunt, W.P., Gam. Res.. 23: 103-118 (1989) and O'Rand, M.G., et al.. Dev. Biol.. 129: 231-240 (1988)). The guinea pig sperm surface protein PH-20 has been shown to have a required function in sperm adhesion to the extracellular coat (zona pellucida) of the egg, a necessary initial step in fertilization. In male and female guinea pigs immunized with PH-20, 100% effective contraception was obtained. Antisera from immunized females had high titers, specifically recognized PH-20 in sperm extracts and blocked sperm adhesion to egg zona pellucida, in vitro. The contraceptive effect was long- lasting and reversible; immunized females mated at intervals of 6-15 months after immunization progressively regained fertility. A second guinea pig sperm surface protein, PH-30, has also shown a contraceptive effect. Other sperm proteins tested as contraceptive immunogens include the sperm enzymes hyaluronidase, acrosin and lactate dehydrogenase C-4. Immunization of female animals with these enzymes had either no effect on fertility or partial effects on fertility, which were not large enough to make these proteins suitable as contraceptive agents. The high contraceptive effectiveness of PH-20, in the guinea pig, seems to depend on several of its specific properties, including its presence on the sperm surface, its strong immunogenicity and its essential role in fertilization. Mammalian sperm-zona adhesion is in most cases species specific. Sperm from other mammalian species are like guinea pig sperm in that they can bind to the zona pellucida either before or after the acroso e reaction. The identification and isolation of sperm surface proteins essential for fertilization in species other than guinea pig would be useful for developing vaccines for effective immunization and providing long lasting contraception in those species. The lack of biochemical identification, isolation and cloning of candidate adhesion proteins of sperm has hindered scientists in developing effective contraceptive vaccines for humans as well as other mammalian species. Summary of the Invention The subject invention relates to methods of contraception in which one or more sperm surface proteins is administered to a mammal. The sperm surface protein (or portion of same) is administered in an amount effective for the stimulation of an immune response whereby antibody which binds to the sperm surface protein is produced in a titer sufficient to prevent or substantially reduce the rate of sperm-egg fusion. The protein, or protein fragment, can be purified by conventional methods, or produced by recombinant DNA methodology. The invention also relates to contraceptive compositions for use in the methods described herein. These compositions contain a sperm surface protein, or a portion thereof. Preferred sperm surface proteins are the PH-20 and PH-30 sperm surface proteins.

Detailed Description of the Invention The subject invention relates to sperm surface proteins which are essential for fertilization, or portions thereof, and their use in contraceptive methods. A sperm surface protein is essential for fertilization if, for example, a monoclonal antibody to the protein or a polyclonal antibody raised against the purified protein, when bound to sperm, inhibits jln vitro or .in vivo fertilization or any step in vitro fertilization. The process of fertilization is defined as the binding or fusion of two gametes (sperm and egg) followed by the fusion of their nuclei to form the genome of a new organism. The surface protein can be located in the plasma membrane of sperm and/or the inner acrosomal membrane. It can be a protein or glycoprotein. The isolated surface protein used for immunization can comprise the entire surface protein or some portion of the protein (external to the cell) which is immunogenic. Preferred sperm surface proteins are the PH-20 and PH-30 sperm surface proteins. Both the PH-20 and PH-30 genes encode proteins which are present on the surface of sperm cells and are essential for fertilization. It has been determined that the DNA encoding PH-20 in one mammalian species is cross- reactive (i.e., hybridizable) with genomic DNA from all other mammals tested. The existence of these homologues in other mammalian species was an unexpected finding since mammalian sperm-zona pellucida adhesion is, in most cases, species specific. Similarly, guinea pig PH-30 cDNA hybridizes with human genomic DNA. Production and Purification of Iπαnunogen A preferred method for producing sperm surface proteins for use as a contraceptive immunogen is by recombinant DNA technology. To produce the protein using this technology it is necessary to isolate and clone DNA encoding the protein, or an immunogenic portion thereof. Those skilled in the art are familiar with a variety of approaches which can be used in an effort to clone a gene of interest. However, having nothing more than the isolated protein of interest, success in such an effort can not be predicted with a reasonable degree of certainty. In Example 1 which follows, Applicants' report the isolation and cloning of DNA encoding the guinea pig PH-20 gene. The method used to isolate DNA encoding the 3' portion of the PH-20 gene involved the screening of a cDNA expression library with polyclonal sera reactive with the PH-20 protein. Anchored PCR was used to isolate the 5' portion of the gene. Example 2 reports the surprising finding that a broad spectrum of mammalian genomic DNA contains DNA sequences which hybridize to guinea pig PH-20 sequences under the hybridization conditions described. In fact, cross- reacting sequences were identified in each of the mammalian samples analyzed. The information presented in Examples 1 and 2, enable one skilled in the art to isolate and clone the PH-20 gene from any mammalian species. For example, a cDNA library is prepared from testis or spermatogenic cells isolated from a mammal of interest (e.g., feline, equine, canine, bovine, etc.). This can be a time consuming process, but it is technically straightforward. One skilled in the art would approach this task with a high degree of certainty with regard to success. Such a cDNA library is then screened using, for example, labeled guinea pig PH-20 DNA probes. DNA encoding all or a portion of PH-20 is characterized by the ability to hybridize to such a probe sequence under hybridization conditions such as those described in Example 2. Methods of labeling and screening by hybridization are very well known in the art. Positive clones are analyzed, and a full length cDNA is constructed by conventional methods. In light of Applicants' teaching that each of the 7 mammals analyzed contained cross- hybridizing sequences, one skilled in the art would expect all mammals to contain cross-hybridizing species. It is this methodology which enabled Applicants to isolate and clone the murine and human PH-20 genes, as described in greater detail below. The cloned gene, or portions thereof which encode an immunogenic region of the PH-20 protein, can be expressed by inserting the coding region into an expression vector to produce an expression construct. Many such expression vectors are known to those skilled in the art. These vectors contain a promoter for the gene of interest as well as additional transcriptional and translational signals. Expression vectors for both eukaryotic host cells and prokaryotic host cells are widely available. The DNA expression construct is used to transform an appropriate host cell. Eukaryotic, in particular mammalian, host cells are preferred for the expression of the sperm surface protein. It has been found, for example, that eukaryotic proteins frequently exhibit folding problems when expressed in prokaryotic cells. In addition, production of authentic, biologically active eukaryotic proteins from cloned DNA frequently requires post-translational modification such as disulfide bond formation, glycosylation, phosphorylation or specific proteolytic cleavage processes that are not performed in bacterial cells. This is especially true with membrane proteins. The sperm surface protein is produced using the transcriptional and translational components of the host cell. After an appropriate growth and expression period, the host cell culture is lysed and the sperm surface protein is purified from the lysate. Lysis buffers typically include non- ionic detergent, protease inhibitors, etc. From the solubilized cell extract, the sperm surface protein can be purified and isolated by physical and biochemical methods such as ultracentrifugation, column chromatography, high performance liquid chromatography, electrophoresis, etc. Alternatively, the sperm surface protein can be isolated by affinity chromatography using monoclonal or polyclonal antibodies (see Primakoff et al.. Biol. of Reorod. 38: 921-934 (1988)). Such methods for purifying proteins are well known to those skilled in the art. The methods outlined above with respect to the PH-20 gene and gene product are also applicable to the PH-30 gene and gene product. The isolation of DNA encoding the o and β subunits of the PH-30 sperm surface protein is described in Example 5. Methods analogous to those described above can be used to isolate and express mammalian homologues to the guinea pig PH-30 protein. It can be predicted with a high degree of certainty that DNA encoding the guinea pig PH-30 sperm surface protein can be used as a probe to isolate homologous sequences from other mammals. This prediction is based on the fact that guinea pig DNA has been used to identify the presence of a PH-30 homologue in human genomic DNA. As mentioned above, antigenic portions of the sperm surface protein are useful as immunogen, in addition to the full length protein. Antigenic fragments can be produced, for example, by proteolytic digestion of the full length protein, followed by isolation of the desired fragment. Alternatively, chemical synthesis can be used to generate the desired fragment starting with monomer amino acid residues. With respect to the PH-30 protein, certain antigenic domains are preferred candidates for use in a contraceptive vaccine. As is discussed in greater detail in the Exemplification section which follows, the PH-30 β subunit contain a domain which is highly conserved when compared to a class of proteins known as disintegrins. A peptide (or portion thereof) which is identical or substantially identical to this domain is preferred for use in the contraceptive methods of this invention. Substantially identical, as used in the preceding sentence, means that at least 80% of the amino acid sequence of the peptide is identical to the corresponding portion of the PH-30 β disintegrin domain. Disintegrins are found in snake venom, for example, and are known to bind to a class of platelet surface proteins known as integrins. The binding of disintegrins to integrins has been shown to inhibit blood clotting. By analogy, peptides corresponding to the PH-30 β disintegrin domain are predicted to be active in sperm-egg binding and fusion. Contraceptive Vaccine Once the sperm surface protein has been produced and purified, a vaccine can be produced by combining the sperm surface protein with a suitable carrier for administration to a subject for immunization. A vaccine can contain one or more sperm surface proteins. Sperm surface proteins of the present invention can be combined with adjuvants which contain non-specific stimulators of the immune system. Proper use of adjuvants can induce a strong antibody response to foreign antigens (i.e., sperm surface proteins) . The action of adjuvants is not fully understood, but most adjuvants incorporate two components. One is a substance designed to form a deposit which protects the antigen from catabolism. Two methods of forming a deposit are to use mineral oils or aluminum hydroxide precipitates. With mineral oils, such as Freund's adjuvant, the immunogen is prepared in a water- in-oil emulsion. For aluminum hydroxide, the immunogen is either adsorbed to preformed precipitants or is trapped during precipitation. Alternative delivery systems include liposomes or synthetic surfactants. Liposomes are only effective when the immunogen is incorporated into the outer lipid layer; entrapped molecules are not seen by the immune system. The second component required for an effective adjuvant is a substance that will stimulate the immune system nonspecifically. These substances stimulate the production of a large set of soluble peptide factors known as lymphokines. In turn, lymphokines stimulate the activity of antigen-processing cells directly and cause a local inflammatory reaction at the site of injection. A component of lipopolysaccharide known as lipid A is commonly used. Lipid A is available in a number of synthetic and natural forms that are much less toxic than lipopolysaccharides, but still retain most of the desirable adjuvant properties of the lipopolysaccharide molecules. Lipid A compounds are often delivered using liposomes. The two bacteria that are commonly used in adjuvants as non-specific stimulants are Bordatella pertussis and Mycobacterium tuberculosis. When used as whole bacteria, they must be heat-killed prior to use. The immunomodulatory mediators of B. pertussis include a lipopolysaccharide component and the pertussis toxin. The pertussis toxin has been purified and is available commercially. M. tuberculosis is commonly found in complete Freund's adjuvant. The most active component of M. tuberculosis has been localized to muramyl dipeptide which is available in a number of forms. Immunizations (Inoculation and Booster Shots) The subject to be immunized can be any mammal which possesses a competent immune system. Examples of subject mammals include humans and domestic animals (e.g., dogs, cats, cows, horses, etc.), as well as animals intended for experimental or other purposes (e.g., mice, rats, rabbits, etc.) . Two different criteria are important to consider in determining the proper dose for the initial immunization. First, the optimum dose to achieve the strongest response and second, the minimum dose likely to induce the production of useful polyclonal antibodies. Much of the injected material will be catabolized and cleared before reaching the appropriate target immune cell. The efficiency of this process will vary with host factors, the route of injection, the use of adjuvants, and the intrinsic nature of the surface protein injected. Thus, the effective dose delivered to the immune system may bear little relationship to the introduced dose and consequently dose requirements must be determined empirically. These determinations can be readily made by one skilled in the art. Secondary injections and later boost can be given with amounts similar to or less than the primary injection. The route of injection is guided ' y three practical decisions: 1) what volume must be de_. ^red; 2) what buffers and other components will be injected with the immunogen; and 3) how quickly should the immunogen be released into the lymphatics or circulation. For example, with rabbits, large volume injections normally are given at multiple subcutaneous sites. For mice, large volumes are only possible with intraperitoneal injections. If adjuvants or particulate matter are included in the injection, the immunogen should not be delivered intravenously. If a slow release of the inoculant is desired, the injections should be done either intramuscularly or intradermally. For immediate release, use intravenous injections. Primary antibody responses often are very weak, particularly for readily catabolized, soluble antigens. Hence, secondary or booster injections are required after the initial immunization. A delay is needed before reintroducing the protein into a primed subject. A minimum of 2 or 3 weeks is recommended but greater intervals are possible. The antibody responses to secondary and subsequent injections is much stronger. Higher titers of antibody are reached, but more importantly, the nature and quantity of the antibodies present in serum changes. These changes yield high- affinity antibodies. The intervals between secondary, tertiary and subsequent injections may also be varied, but usually need to be extended to allow the circulating level of antibody to drop enough to prevent rapid clearance of newly injected antigen. Subsequent booster injections will be required to increase reduced circulating antibody for continued contraception. The actual intervals for these injections will differ form species to species. However, the intervals can be determined by one skilled in the art by monitoring serum levels of sperm surface protein antibodies. In another embodiment, subjects can be administered with alloantisera, or monoclonal antibodies, directed to a sperm surface protein to achieve contraception. The alloantiserum is raised in another individual of the same species, isolated from the serum of the individual and prepared in a suitable carrier for injection into the recipient subject. Those skilled in the art are familiar with methods for preparing and formulating monoclonal antibodies for administration. The present invention is further explained in the following exemplification. EXAMPLES Example 1: Isolation of DNA Encoding Guinea Pig PH-20 Library construction and screening A population of guinea pig testicular cells, enriched for spermatogenic cells on a Percoll gradient was used for the isolation of spermatogenic cell total RNA. The pelleted cells were lysed with detergent in the presence of vanadyl-ribonucleoside complexes (VRC) in 0.5-1.0 ml of solution containing lOmM Tris (pH 8.6), 0.5% NP-40, 0.14 M NaCl, 1.5 mM MgCl 2 and lOmM VRC. After pelleting cellular debris, 0.5 volume of 2X Proteinase K buffer (2X=0.2M Tris (pH 7.5), 25 mM EDTA (pH 8.0), 0.3 M NaCl, and 2.0% SDS) and 200 μg/ml Proteinase K was added to the supernant. PolyA+ RNA was purified from the total RNA by oligo-dT cellulose chromatography. cDNA was synthesized using standard methods. Size selected cDNA (0.5-7kb) was ligated with lambda gtll arms and packaged into lambda coat proteins, utilizing kits and protocols from Amersham Corporation. The unamplified library was plated at 20,000 plaques/150 mm plate for screening. A single nitrocellulose filter from each plate was immunoblotted with rabbit anti-PH-20 polyclonal antiserum, raised against affinity-purified PH-20 protein (Primakoff et al.. Biol. Reorod. 38:921-934 (1988)), and diluted 1/500 in TBST (lOmM Tris (pH 8.0), 0.15 M NaCl, 0.05% Tween-20) containing 2 mg/ml E_j_ coli protein. The ________ coli protein was prepared by pelleting an overnight culture of Y1090 cells, resuspending the cells in a minimal volume of TBST and freezing in liquid nitrogen. The thawed cells were sonicated and the protein concentration determined using the BCA reagent (Pierce Chemical) . Six positive plaques were detected with an anti-rabbit IgG alkaline phosphatase-conjugated second antibody (Promega Biotec) . Size of the fusion protein made by plaque-purified positive clones was determined to vary between 118-157 kD as determined by the analysis of J . coli extracts containing the fusion protein on SDS-PAGE. Inserts from the six positive clones were subcloned into pUC19 and sequenced at least partially. Two of the inserts were confirmed to code for the PH- 20 protein by locating the sequences of two PH-20 try ' -; peptides in their derived amino acid sequence. Both these inserts (gpPH-20-1, nucleotide (nt) 1016-2152 and gpPH-20-2, nt 1010-2125, Figure 1 and 2) contained a long (~925 nt) open reading frame, a stop codon, a 3' untranslated region and a polyA tail. Thus these two inserts were concluded to represent the 3' end of a cDNA for PH-20. The other four antibody-positive lambda clones were unrelated to PH-20. The 5' portion of the PH-20 cDNA was cloned utilizing anchored PCR following the protocol of Frohman et al. (Proc. Natl. Acad. Sci. USA 85: 8998-9002 (1988)). PolyA+ RNA from spermatogenic cells (2μg in 10 μl dH 2 0) was heated to 65°C for 3 min and then reverse transcribed by adding 4 μl 10 X RTC buffer (IX buffer is 50 mM Tris (pH 8.3), 50 mM KCl, 4 mM dithiothreitol, 10 mM MgCl 2 ) ) , and 4 μl 10 mM stock of each dNTP (1 mM final), 2 μl of 80 mM sodium pyrophosphate (4 mM final) , 1 μl (40 units) of RNasin (Promega Biotec) , 40 pmol PH-20 specific primer (PH-20-RT) , 18 units AMV reverse transcriptase (Life Sciences) and 40 μCi 32P-dCTP in 40 μl total volume. After 1 hour of incubation at 42°C, an additional 1 μl of reverse transcriptase was added and incubation continued for a second hour. The PH-20-RT primer was a 17 nucleotide (nt) oligomer (nt 1242-1258, Figure 2), -250 bases downstream from the 5' end of the insert gpPH-20-1 (Figure 1) . The single strand cDNA was separated from excess PH- 20-RT by column chromatography, tailed with polyA and diluted to 1.0 ml. Second strand synthesis and PCR amplification were performed with a GeneAmp kit (Perkin Elmer Cetus) in a 100 μl reaction containing 10 μl of the reverse transcription product, 20 pmol (dT) 17 adapter, 50 pmol adapter and 50 pmol PH-20-AMP primer. The PH-20-AMP primer was a 17 nt oligomer (nt 1202-1218, Figure 2) located upstream from the PH-20-RT primer. The PCR product was purified from unincorporated primers and free nucleotide by spin column chromatography (columns from Boehringer-Mannhei ) . It was subsequently digested with HgiA I and Sal I, gel purified and ligated into pBluescript digested with Pst I and Sal I. The major PCR product was 1.2 kb, and Southern Blot analysis confirmed that this band hybridized with the labeled insert gpPH-20- 1. The major PCR products from three separate reactions were cloned and one insert from each of the three reactions was sequenced (gpPH-20-3, nt 1-1175, gpPH-20-4, nt 24-1175 and gpPH-20-5, nt 295-1175). The complete cDNA sequence and the deduced amino acid sequence were obtained from the five cDNA inserts (Figure 2) that were sequenced in their entirety on both strands. The cDNA sequence contains a 354 nt 5' untranslated region, a 1590 nt open reading frame, and a 208 nt 3' untranslated region. The derived amino acid sequence contains all the tryptic peptide sequences obtained from purified PH-20, confirming that the cDNAs are authentic PH-20 clones. Hybridization experiments indicated that guinea pig genomic DNA contained a single gene for PH-20. Computer searches revealed no significant homology of the guinea pig PH-20 amino acid sequence with other known sequences. Example 2: PH-20 Homologues in Other Mammalian Species To determine if there is a ho ologue of the PH-20 gene in the genomic DNA of other species, cross species Southern blots were performed. Genomic DNA was isolated from guinea pig, rat, rabbit, mouse, and hamster spleens by detergent lysis-Proteinase K digestion. Other DNA samples (i.e., human, monkey and chicken) were provided by other investigators at the University of Connecticut Health Center. DNA from salmon sperm and bovine thymus were purchased from Sigma and reconstituted at 1 mg/ml in TE (10 mM Tris (pH 8.0), 1 mM EDTA (pH 8.0)). All species DNA's (lOμg) were cut with restriction enzymes and separated on a 1% agarose gel. The Southern transfer was carried out by capillary transfer onto nylon membrane. The membranes were prehybridized in a solution consisting of 6XSSC, IX Denhardt's, 250 mg/ml salmon sperm DNA, 1% SDS, and 50 mM NaP0 4 (pH 7.4), for 1-2 hours at 65°C. The membranes were hybridized overnight at 55°C in prehybridization buffer plus 2 x 10 6 cpm/ml probe. Probes were prepared by the random hexamer method. The blot was washed 3 X 5 min in 2XSSC + 1.0% SDS at room temperature, 2 X 30 min in 2XSSC + 0.1% SDS at room at 50°C, and 2 X 30 min in 1XSSC + 0.1% SDS at 60°C. The blot was wrapped in plastic wrap and exposed to film with an intensifying screen at -70°C. The blots were probed with a mix of labeled gpPH-20-3 and gpPH-20-2. The Southern blots exhibited a weakly hybridizing band at -10 kb for chicken DNA and strongly hybridizing bands for mouse, rat, hamster, rabbit and human DNA. In addition, hybridization was observed with bovine and monkey DNA. Example 3: Isolation of DNA Encoding Mouse PH-20 PolyA+ RNA was isolated from murine round spermatids and used to produce a cDNA library in lambda J using conventional methods. The library was screened using a labeled full length guinea pig PH-20 cDNA probe. The probe was produced by first isolating guinea pig PolyA+ RNA. An oligo-dT primer was hybridized to the poly(A) tract and reverse transcriptase was used to generate a first cDNA strand. Two oligonucleotides, a first being complementary to a portion of the guinea pig PH-20 5' untranslated region and a second being complementary to the 3' untranslated region, were added to the reaction mixture and a full length double stranded DNA sequence containing the entire coding region was generated by polymerase chain reaction. The product of this reaction was a double stranded DNA fragment of between 1.5-1.6 kb. The fragment was cloned and the cloned fragment was analyzed to confirm that it did, in fact, encode the guinea pig PH-20 protein. Labeled probe was generated from this clone by conventional methods. The urine cDNA library was screened using the guinea pig probe described above. Two positive clones were identified. The two clones represent about 1500 base pairs of DNA. Neither of the clones contained sequences from the 5' portion of the cDNA. Anchored PCR using a set of primers complementary to the 5' end of one of the positive clones was used to clone the 5' portion of the murine gene. The DNA sequence is set forth in Figure 3. Example 4: Isolation of DNA Encoding Human PH-20 DNA encoding human PH-20 was isolated and cloned by screening a human testis library in lambda gtll. The library was plated at a density of about 3,000 plaques per 90mm plate. Phage plaques were transferred to duplicate filters and screened with a mix of two radioactively labeled DNA probes, a mouse PH-20 cDNA and a guinea pig PH-20 cDNA. More specifically, the guinea pig probe was the labeled full length guinea pig PH-20 probe described above and the murine clone was one of the two murine clones which lacked sequences from the 5' end of the murine cDNA. Positive plaques that hybridized with the mix of two probes were picked and purified. The cDNA inserts were subcloned and the DNA sequence determined using standard techniques. Two cDNA clones were obtained. Each of the two encode a different form of human PH-20. One human clone is designated H18 (Figure 4) and one is designated H16 (Figure 5) . H18 is a full-length clone which contains an open reading frame of 510 amino acids and short 5' and 3' untranslated regions. The protein encoded in the open reading frame of H18 is 59% identical and 74% similar (includes conservative substitutions) to guinea pig PH-20. H16 is a partial length clone that encodes the carboxyl terminal half of human PH-20. Nucleotide 1 in H16 corresponds with nucleotide 814 in H18. The sequence of H16 from nucleotide 1-781 is identical to the sequence of H18 from nucleotide 814-1594; the sequence of H16 beginning at nucleotide 782 and continuing to nucleotide 1675 is different from the sequence of H18 beginning at nucleotide 1595 and continuing to nucleotide 1696. In terms of the encoded PH-20 protein, the partial protein encoded by H16 is identical to the protein encoded by H18 between amino acids 236-496 (amino acid numbering based on H18 sequence) . H16 then encodes amino acids 497-511 and H18 encodes amino acids 497-510 and the sequences are different at each residue. Expression and Purification of Human PH-20 The full-length clone for PH-20 (H18) was subcloned into two ]______. coli expression vectors, pMAL-p and pMAL-c (New England Biolabs, Beverly, MA) . In both vectors, PH- 20 is made as a fusion protein, the N-terminal fusion partner being the maltose binding (MBP) protein of _______ coli. In pMAL-p, the encoded MBP (which is normally a periplasmic protein) has its usual signal sequence which results in the MBP-PH-20 fusion being targeted to the periplasm. For fusion proteins that can be successfully exported to the periplasm, this location has the advantage that disulfide bonds form (twelve cysteines are present in human PH-20) yielding a potentially more immunogenic protein. In pMAL-c, the signal sequence for MBP is not present, and the fusion protein is found in the cytoplasm and does not form disulfides. Human PH-20 is produced from both pMAL-p and pMAL-c. However, in pMAL-p carrying strains, the amount of hPH-20 made is low, whereas in pMAL-c carrying strains, the amount of PH-20 made is high (the fusion protein is the major band in an EL. coli extract on a Coo assie blue-stained SDS-PAGE gel) . To purify the human PH-20 fusion protein, the MBP-PH-20 fusion protein is bound to an amylose resin (to which MBP binds) and eluted with maltose. Example 5: Isolation of DNA Encoding PH-30 Sperm Surface Protein This Example describes the isolation of DNA encoding the PH-30 sperm surface protein. The subject matter of this example was published by Blobel et al. (Nature 356: 248 (1992)). The mature PH-30 protein is a dimeric protein having an α and a β subunit. The mature PH-30 protein was affinity-purified as described by Primakoff et al. (J. Cell. Biol. 104: 141-149 (1987)). Following isolation, subunits were separated by SDS-PAGE and electroe uted using a Schleicher and Schuell elutrap. Amino-terminal and internal peptide sequences were determined from PH-30 α and β subunits as they occur on fertilization-competent (mature) sperm (see Blobel et al.. J. Cell Biol. Ill: 69- 78 (1990)). To determine N-terminal peptide sequence, the eluted protein was reduced and purified by reverse-phase HPLC. For internal peptide sequence of the α subunit, the eluted, reduced protein was cleaved with trypsin before HPLC. Peptides were sequenced by automated Edman degradation using an Applied Biosystems gas phase sequencer. For the a subunit, the sequences determined were YCTGQSGKCPLDTYKQDG (SEQ ID NO 24) and ALFAAIQIPHGDD (SEQ ID NO 30) . These two peptide sequences were used to design degenerate oligonucleotide primers for nested polymerase chain reactions (PCR) on guinea pig testis cDNA. The primer identity and combinations are specified more particularly in Blobel et al. (Nature 3_56:284 (1992)). The nested PCR product, a band of 308 nucleotide, was subcloned, sequenced and shown to encode the previously determined peptide sequences. The nested RACE protocol was then carried out to complete the 3' sequence of mature PH-30 α and to confirm the peptide sequence of the mature N-terminus. Amplifed DNA fragments were excised from an agarose gel, purified with Geneclean (Bio 101, Inc.), and directly sequenced. Both strands were sequenced with primers spaced at about 175 nucleotide intervals; the secondary reaction products from two different primary RACE reactions were identical. The deduced amino-acid sequences of the PCR products were found to include previously determined peptide sequences. The remainder of the a sequence was generated by a nested rapid amplification of cDNA ends (RACE) protocol (Frohman and Martin, Techniques ! '• 165-170 (1989)). The deduced sequence of the PH-30 a subunit is shown in Figure 6. The nucleotide sequence of the subunit contains one open reading frame encoding 289 amino acids. The sequence of the β subunit was determined in a similar manner. Peptide sequences were determined as described for the a subunit but to generate N-terminal peptide sequence, the β subunit was transferred to an immobilon membrane. To generate internal peptide sequence, the eluted protein was cleaved with cyanogen bromide or V8 protease, electrophoresed, and transferred to immobilon. Alternatively, eluted protein was digested sequentially with CNBr and trypsin, followed by reverse- phase HPLC. The peptide sequences determined by these methods were SNPV_GNNRVEQGEDCDCGSQEECQDTC (SEQ ID NO 22), AQGP (SEQ ID NO 16) , STDECDLPEYCNGSSGACQEDL (SEQ ID NO 16), MGSVD_FEQL_TKNDIT_N (SEQ ID NO 27), A_GASNWK (SEQ ID NO 31), M_IYA_ISG (SEQ ID NO 31), SAL VR (SEQ ID NO 34), C_PS_VCR (SEQ ID NO 34) and VATV (SEQ ID NO 39) . Peptides SNPV_GNNRVEQGEDCDCGSQEECQDTC (SEQ ID NO 22) and STDECDLPEYCNGSSGACQEDL (SEQ ID NO 16) were used to design four degenerate oligonucleotide primers. Nested PCR using combinations of the degenerate primers resulted in two strong bands of 185 and 206 base pairs. The 206-base pair fragment was excised from a polyacrylamide gel, eluted in water, precipitated, sequenced and found to encode PH-30 β peptide sequences. It was labeled with 32P and used to probe an expression library of guinea-pig spermatogenic cell cDNA (Lathrop et al.. J. Cell. Biol. Ill: 2939-2941 (1990)) using high stringency hybridization and wash conditions. One clone, which encoded all of mature PH-30 β plus 4 amino acids of the precursor domain was identified out of 500,000 plaques and directly sequenced using PCR-amplified DNA fragments with primers spaced at about 200 nucleotide intervals. The sequence was confirmed by sequencing both strands of mature PH-30 β amplified by PCR from first strand guinea-pig testis cDNA. The deduced cDNA sequence of the PH-30 β subunit is shown in Figure 7. The nucleotide sequence of the β subunit contains one open reading frame encoding 353 amino acids. Most viral fusion proteins contain a "fusion peptide", either at the N terminus or within the polypeptide, the sequence of which is highly conserved within, but not between, virus families. Fusion peptides are (1) always located in a membrane-anchored subunit, (2) relatively hydrophobic and (3) capable of being modeled as a "sided" α helix with most of the bulky hydrophobic residues on one face. In at least one case, a helical structure is adopted when the fusion peptide interacts with a membrane surface. The hydrophobic face of the helix may mediate virus-cell membrane interactions that lead to fusion. PH-30 α contains a region (residues 90- 111 in Figure 8b) that fulfills all three of these criteria of an internal fusion peptide. Putative internal viral fusion peptides have prolines at or near their centers, similarly, this region has two prolines in the middle of its predicted helix which probably causes a kink, as do prolines in other membrane-interactive α helices. This potential fusion peptide of PH-30 α overlaps another PH-30 region (residues 82-102 in Figure 8b) that is similar in sequence to a potential fusion peptide of the E2 glycoprotein of rubella virus (GADTRCGRLICGLSTTAQYPPTR) (SEQ ID NO 42). Most viral proteins are responsible for binding as well as fusion, to target membranes. The N-terminal 90 amino acids of mature PH-30 β contains a putative integrin-binding "disintegrin" domain that could function in the membrane-binding step that precedes sperm-egg fusion. Disintegrins such as bistatin (Shebuski et al.. J. Biol. Chem. 264:21550-21556 (1989)) barbourin (Scarborough et al. J. Biol. Chem. 266:9359-9362 (1991)), kistrin (Dennis et al. Proc. Natl. Acad. Sci. 86:4022-4026 (1989)) and echistatin (Gan et al. J. Biol. Chem. 263:19832 (1988)) comprise a family of short (49-83 amino acids) , soluble and highly conserved platelet aggregation inhibitors from snake venoms which act by competitive inhibition of fibrinogen binding to the integrin gpIIb/IIIa. The similarity of sperm PH-30 β to these integrin ligands suggests that it binds to a receptor, probably an integrin, on the egg plasma membrane. Most disintegrins contain an integrin consensus binding sequence RGD. Changes in this sequence alter either the affinity (Garsky et al.. Proc. Natl. Acad. Sci. 8j>.4022-4026 (1989)), or the specificity of binding (Scarborough et al.. J^ Biol. Chem. 2_6£:9359-9362 (1991), Phillips et al.. Cell 6_5:359-362 (1991)). Half of the known integrin ligands, however, either do not contain this tripeptide or can interact with integrins using non- RGD sequences. Nuclear magnetic resonance analysis revealed that the RGD sequences of kistrin and echistatin are at the tip of a loop where they are thought to assume a conformation necessary for high-affinity binding. If the disintegrin domain of PH-30 β adopts a similar tertiary structure, the sequence TDE and an additional (odd-numbered) cysteine would occupy the tip of such a loop and might then interact with an integrin on the egg plasmal membrane. The disintegrin domain of the longer snake venom protein HR1B contains the sequence ESE and an additional cysteine in this position. Two lines of indirect evidence support the hypothesis that PH-30 β binds to an egg plasma membrane integrin: proteolysis of mouse eggs reduces their fertilization competence (Calarco Microscope Tech. 1/7:401-411 (1991), Boldt et al.. Gamete Res. 22:91-101 (1989)), and two of the implicated egg surface polypeptides have a molecular weight of 95K and 150K, similar to the α and β integrin subunits; also micromolar concentrations of RGD-containing peptides inhibit fusion between human or hamster sperm and hamster eggs lacking a zona pellucida. RGD peptides might compete with PH-30 homologues on these sperm, even if the homologues do not contain an RGD sequence, as RGD peptides can compete for binding of non-RGD integrin ligands. Example 6: Contraceptive Vaccination bv the Administration of PH-30 Protein The identification and purification of the guinea pig sperm surface protein PH-30 has been described by Primakoff et al. (J. Cell. Biol. 104: ,L41 (1987)). This Example describes the results of experiments in which both male and female guinea pigs were immunized with purified PH-30 protein, and the effect of this immunization on fertility. Female or male Hartley guinea pigs (about 300 grams (females) or 600-650 grams (males) at the time of first injection) received two injections of PH-30 in the amounts stated below. PH-30, purified from sperm by mAb-affinity chromatography, showed no detectable contaminants using silver-staining of purified protein on SDS gels. Purity of each PH-30 preparation used for immunization of females or males was verified by SDS polyaerylamide gel electrophoresis and silver staining. The affinity- purified PH-30, in 0.375 ml phosphate-buffered saline (PBS) containing 3 mM octyglucoside (OG) was emulsified with 0.375 ml complete Freund's adjuvant (CFA) . Each animal received 0.5 ml of the emulsion subcutaneously in the back and 0.25 ml intramuscularly in a rear leg. About 1 month later the same amount of PH-20 in PBS and 3 mM OG was emulsified with incomplete Freund's adjuvant (IFA) , and was injected in the same sites in each animal (the following exceptions apply: males 1 and 3 received only one injection) . Control females and males received the same injections on the same schedule and containing PBS and 3 mM OG and CFA or IFA, but lacking PH-30. To allow the injected females to mate, about two months after the initial injection they were housed with males for 3 weeks. Each cage contained one male (575-600 g) , one PH-30 immunized female, and from 2-4 control injected females. After three weeks, the females were separated from the males, pregnant females had litters and progeny were counted. Control-injected females that failed to become pregnant had been in cages where the other controls did become pregnant, indicating that all the males mating with immunized females were fertile. To allow the injected males to mate, about four months after the initial injection, each injected male was housed with two females (about 600 grams) for three weeks. The females and males were then separated and after an additional 5 weeks females were killed and fetuses counted. The results of these experiments are set forth in the tables which follow. TABLE l! Immunized Females Table 1 shows that of the 6 female guinea pigs which were immunized, four were fertile. Of the control- injected females, 34 of 36 were fertile. TABLE 2: Immunized Males Table 2 shows that of the 3 males guinea pigs which were immunized, all 3 were infertile. Of the control- injected males, 5 out of 5 were fertile. Example 7: Use of PH-30 Disintegrin Peptides as Inhibitor of Sperm Fusion to Egg Plasma Membrane Peptides from the PH-30 β disintegrin domain were tested for inhibition of sperm binding to the egg plasma membrane. More specifically, two modified PH-30 β peptides were tested. These two peptides contain the sequence TDE which is in the same position in the disintegrin domain as RGD, the active tripeptide in most snake disintegrins. The two modified PH-30 peptides tested were STDECDLK (SEQ ID NO 43) and CSTDEC (SEQ ID NO 44) . The first of the two peptides is a linear peptide and was modified by the addition of a lysine residue (K) to facilitate conjugation of the peptide to an agarose bead. The second of the two peptides is a cyclized peptide and was modified by the addition of a cysteine residue (C) to allow cyclization by disulfide formation. Two control peptides, which represent a random string of amino acids, were also included in the fusion inhibition assay. The control peptides were GRGDTP (SEQ ID NO 45) and GRGES (SEQ ID NO 46) . The fusion inhibition assay was carried out as follows. Eggs were collected from guinea pig ovaries. The eggs were incubated in tissue culture medium overnight. The zona pellucida was removed with a mixture of proteases. The zona pellucida free eggs were incubated in culture media with peptide at a specified concentration for 30 minutes. Sperm collected from the epididymis of male guinea pigs was capacitated by incubation and acrosome reacted as described by Fleming and Yanagimachi (Gamete Res. 4.: 253- 273 (1981)) and added to the eggs and incubated for 15 minutes. The eggs were then transferred to a sperm free culture medium and incubated for an additional 1 hour and 45 minutes. The eggs were then fixed and stained as described by Primakoff et al. (J. Cell. Biol. 104: 141 (1987)). The total number of swollen sperm heads were then counted. Swollen sperm heads are an indication that the sperm and egg have fused. On the basis of these observations, several indices are calculated. The fertilization index (F.I.) is determined by dividing the total number of swollen heads by the total number of eggs. The fertilization rate (F.R.) is the percentage of eggs fertilized. The percent inhibition is determined by dividing the fertilization index of the experimental peptide by the fertilization index of the control peptide. The data obtained from the sperm-egg fusion inhibition assay are summarized in Tables 3-6 below. The results of these experiments show clearly that compared to no peptide, incubation of the zona pellucida free eggs with the control peptides GRGES and GRGDTP results in no significant inhibition of sperm-egg fusion. The fusion rates observed between the no peptide assay and the control peptide assay were similar or were higher in the presence of control peptide (Table 3) . However, when experimental peptides CSTDEC and STDECDLK were strongly inhibited compared to no peptide addition (Table 4) or compared to control peptide addition (Table 5) . When the fertilization index is near the biologically normal level of 1 sperm per egg, STDECDLK inhibits sperm-egg fusion 92% and CSTDEC inhibits 89% (Table 4) . It can be concluded from these data that the PH-30 β disintegrin domain represents an epitope which is critical in sperm-egg fusion. Antibodies which bind specifically to this epitope would be predicted to block sperm/egg fusion.
