Neuropeptide Y (NPY) (3-36) is a C-terminal fragment of NPY, a neuropeptide involved in controlling appetite, blood pressure, cardiac contractility, and intestinal secretion.1 NPY (3-36) is an endogenous peptide produced by cleavage of NPY by dipeptidyl peptidase 4 (DPP-4).2,3 It binds selectively to the NPY receptor Y2 (Ki = 0.41 nM in CHP 234 cells) over the Y1 receptor, where it does not bind at concentrations up to 1 µM. NPY (3-36) (0.1 nM) increases migration of human umbilical vein endothelial cells (HUVECs) by 80% after 12 hours in an in vitro wound closure assay.4 NPY (3-36) corresponds to residues 3-36 of the human and rat protein sequence.WARNING This product is not for human or veterinary use.
