Biological Activity

C-Terminal fragment of xenin, a neurotensin-like peptide; modulates pancreatic insulin and glucagon secretion/effects. Stimulates basal and arginine-induced insulin secretion and potentiates the insulin response to glucose (EC50 = 0.16 nM). Also potentiates arginine- and carbachol-induced glucagon secretion in a somatostatin-independent manner.
