Neuropeptide Y (NPY) is a peptide that is abundant in the central and peripheral nervous system that plays a major role in controlling appetite, blood pressure, cardiac contractility, and intestinal secretion. NPY is a vasonconstrictor that inhibits Ca2+-activated K+ channels in vascular smooth muscle. Inhibition of NPY synthesis regulates food intake and metabolism implicating a role in obesity. This NPY amino acid sequence is homologous for human, rat, rabbit, and guinea pig.
