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+)."}]
