Definition:An oligopeptide comprising of nine amino acids with sequence L-Ile-L-Ala-L-Arg-L-Arg-L-His-L-Pro-L-Tyr-L-Phe-L-Leu. It was originally isolated from pepsin-treated human plasma and shares some sequence homology with the C-terminal end of neurotensin. It is a potent histamine releaser and may serve as an inflammatory mediator.
