Usage And Synthesis

Uses

Kinetensin is a neurotensin-like peptide isolated from pepsin-treated human plasma.

Definition

ChEBI: Kinetensin is 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. It has a role as a human metabolite and a histamine releasing agent. It is a conjugate base of a kinetensin(2+).

in vivo

Kinetensin also induces a dose-dependent increase in vascular permeability when injected intradermally into rats^[2].
