Sauvagine
Neuropeptide
From Wikipedia, the free encyclopedia
Sauvagine is a neuropeptide from the corticotropin-releasing factor (CRF) family of peptides and is orthologous to the mammalian hormone, urocortin 1, and the teleost fish hormone, urotensin 1.[1] It is 40 amino acids in length,[2] and has the sequence XGPPISIDLSLELLRKMIEIEKQEKEKQQAANNRLLLDTI-NH2, with a pyrrolidone carboxylic acid modification at the N-terminal and amidation of the C-terminal isoleucine residue. It was originally isolated from the skin of the frog Phyllomedusa sauvagii. Given its relation to other CRF-related peptides, it exerts similar physiological effects as corticotropin-releasing hormone.[3][4]

Sauvagine belongs to the corticotropin-releasing factor (CRF) family that also includes CRF, urocortin l/urotensin l, urocortin II and urocortin III.[5][1]
Interactions
Sauvagine has been shown to interact with corticotropin releasing factor receptors 1 and 2, and (as with other CRF-related peptides) is also bound by the corticotropin-releasing factor binding protein.[6]
