Abstract: In accordance with the present invention, there are provided novel G-protein-coupled receptor proteins (CRF-R) characterized by having sufficient binding affinity for corticotropin releasing factor (CRF) such that concentrations of £ 10 nM of CRF occupy 350% of the binding sites of said receptor protein. Nucleic acid sequences encoding such receptors, assays employing same, as well as antibodies derived therefrom, are also disclosed. Invention CRF-Rs can be employed in a variety of ways, such as, for example, in bioassays, for production of antibodies thereto, in therapeutic compositions containing such proteins and/or antibodies.

Abstract: Urocortin (Ucn) is a native mammalian peptide generally related to Urotensin I and Corticotropin Releasing Factor (CRF). Human Ucn has the formula: Asp-Asn-Pro-Ser-Leu-Ser-Ile-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Thr-Leu-Leu-Glu-Leu-Ala-Arg-Thr-Gln-Ser-Gln-Arg-Glu-Arg-Ala-Glu-Gln-Asn-Arg-Ile-Ile-Phe-Asp-Ser-Val-NH2 (SEQ ID NO: 15). Rat-derived Ucn is identical but for 2 substitutions, Asp2 for Asn2 and Pro4 for Ser4. Ucn or analogs thereof or pharmaceutically acceptable salts can be administered to humans and other mammals to achieve substantial elevation of ACTH, &bgr;-endorphin, &bgr;-lipotropin, other products of the pro-opiomelanocortin gene and corticosterone. They can also be used to lower blood pressure over an extended period of time, as stimulants to elevate mood and to improve memory and learning performance, as well as diagnostically. Shortened fragments may be administered to release endogenous CRF and/or Ucn in the brain and peripherally.
