摘要:
A purified polypeptide which provides for initial binding of sperm to oocyte investments and has an active amino acid sequence of SEQ ID NO:12 (Cys-Gln-Ser-Leu-Gln-Glu-Tyr-Leu-Ala-Glu-Gln-Asn-Gln-Arg-Gln-Leu-Glu-Ser-Asn-Lys-Ile-Pro-Glu-Val-Asp-Leu-Ala-Arg-Val-Val-Ala-Pro-Phe-Met-Ser-Asn-Ile-Pro-Leu-Leu-Leu-Tyr-Pro-Gln-Asp-Arg-Pro-Arg-Ser-Gln-Pro-Gln-Pro-Lys-Ala-Asn-Glu-Asp-Val-Cys); or SEQ ID NO:13 (Cys-Glu-Ser-Leu-Gln-Lys-His-Leu-Ala-Glu-Leu-Asn-His-Gln-Lys-Gln-Leu-Glu-Ser-Asn-Lys-Ile-Pro-Glu-Leu-Asp-Met-Thr-Glu-Val-Val-Ala-Pro-Phe-Met-Ala-Asn-Ile-Pro-Leu-Leu-Leu-Tyr-Pro-Gln-Asp-Gly-Pro-Arg-Ser-Lys-Pro-Gln-Pro-Lys-Asp-Asn-Gly-Asp-Val-Cys); or the shorter but biologically active SEQ ID NO:1 and SEQ ID NO:9 (Tyr-Pro-Gln-Asp-Arg-X-Arg-Ser-Gln-Pro-Gln-Pro-Lys-Ala-Asn, where X is Thr or Pro). The polypeptide is useful in improving sperm-egg binding by fresh sperm, restoring sperm-egg binding following a cryopreservation cycle, enhancing fertilizing potential, and producing antibodies to determine fertilizing potential of sperm, determining sperm-binding sites on egg investments, and contraception.
摘要:
The present invention relates to a novel t-PALP protein which is a member of the serine protease family. In particular, isolated nucleic acid molecules are provided encoding the human t-PALP protein. t-PALP polypeptides are also provided as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of t-PALP activity. Also provided are diagnostic methods for detecting circulatory system-related disorders and therapeutic methods for treating circulatory system-related disorders.
摘要:
The invention relates to methods and compositions for the treatment of autoimmune disease. Specifically, compositions comprising heat shock proteins, including gp96, hsp90, and hsp70, are disclosed. Immunotherapeutic methods for administering the hsp-containing compositions are disclosed. Furthermore, methods for preventing rejection of organs transplanted to treat autoimmune disease are disclosed. The disclosed methods are useful for treating a variety of autoimmune diseases, including insulin dependent diabetes mellitus.
摘要:
The invention embodies the surprising discovery that Tissue Factor (TF) compositions and variants thereof specifically localize to the blood vessels within a vascularized tumor following systemic administration. The invention therefore provides methods and compositions comprising coagulant-deficient Tissue Factor for use in effecting specific coagulation and for use in tumor treatment. The TF compositions and methods of present invention may be used alone, as TF conjugates with improved half-life, or in combination with other agents, such as conventional chemotherapeutic drugs, targeted immunotoxins, targeted coaguligands, and/or in combination with Factor VIIa(FVIIa) or FBVIIa activators.
摘要:
A partial murine cDNA clone, a human cDNA clone, and a partial human genomic clone, each encoding a Box-dependent myc-interacting polypeptide termed Bin1, are provided. Also provided are methods of using the nucleic acid sequences, polypeptides, and antibodies directed against same in the diagnosis and treatment of cancers and hyperplastic disease states.
