摘要: A human urocortin-related peptide with significant sequence homology to the CRF neuropeptide family was identified. A mouse cDNA was isolated from whole brain poly (A+) RNA that encodes a predicted 38 amino acid peptide protein designated herein as urocortin II. Both human URP and mouse Ucn II are structurally related to the other known mammalian family members, CRF and urocortin (Ucn). These peptides are involved in the regulation of the hypothalamic-pituitary-adrenal axis under basal and stress conditions, suggesting a similar role for URP and Ucn IL Synthesized Ucn-II and URP peptide binds with higher affinity to CRF-R2 than to CRF-R1 Ucn II and human URP appear to be involved in the regulation of body temperature and appetite and may play a role in other stress related phenomenon. These findings identify Ucn II and human URP as a new members of the CRF family of neuropeptides, which are expressed centrally and bind to CRF-R2.

摘要: A search of the public human genome database identified a human EST, GenBank accession number AW293249, which has high homology to known pufferfish urocortin sequences. The full length sequence was amplified from human genomic DNA and sequenced. Sequence homology comparisons of the novel sequence with human urocortin I and urocortin II revealed that the sequence encoded a novel human urocortin, which was designated urocortin III (UcnIII). While urocortin III does not have high affinity for either CRF-R1 or CRF-R2, the affinity for CRF-R2 is greater than the affinity for CRF-R1. Urocortin III is capable stimulating cyclic AMP production in cells expressing CRF-R2α or β. Thus, the affinity is high enough that urocortin III could act as a native agonist of CRF-R2. However, it is also likely that urocortin III is a stronger agonist of a yet to be identified receptor.

摘要: Peptides which inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads. These peptides may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors. The peptides are cyclic analogs of the decapeptide GnRH wherein there is a covalent bond between the residue in the 4-position and the residue in the 10-position. Examples of such bonds include the disulfide linkage between Cys residues, an amide linkage between a side chain amino group and a side chain carboxyl group, a dicarba linkage between side-chain alkyl groups, and a carba linkage between a side-chain alkyl group and a side-chain sulfhydryl group.

摘要: In accordance with the present invention, there are provided novel receptor proteins characterized by having the following domains, reading from the N-terminal end of said protein: an extracellular, ligand-binding domain, a hydrophobic, trans-membrane domain, and an intracellular, receptor domain having serine kinase-like activity. The invention receptors optionally further comprise a second hydrophobic domain at the amino terminus thereof. The invention receptor proteins are further characterized by having sufficient binding affinity for at least one member of the activin/TGF-&bgr; superfamily of polypeptide growth factors such that concentrations of ≦10 nM of said polypeptide growth factor occupy ≧50% of the binding sites of said receptor protein. A presently preferred member of the invention superfamily of receptors binds specifically to activins, in preference to inhibins, transforming growth factor-&bgr;, and other non-activin-like proteins. DNA sequences encoding such receptors, assays employing same, as well as antibodies derived therefrom, are also disclosed.
