neuropeptide y (336) (human, rat)

Neuropeptide Y (3-36) (human, rat) is a metabolite of neuropeptide Y (NPY) generated by dipeptidyl peptidase-4 (DPP4) and is known as a selective Y2 receptor agonist, effectively reducing the release of norepinephrine via the Y2 receptor [1][2].

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. NPY (3-36) is an endogenous peptide produced by cleavage of NPY by dipeptidyl peptidase 4 (DPP-4). 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. NPY (3-36) corresponds to residues 3-36 of the human and rat protein sequence.
