Neuropeptide Y (NPY), peptide YY (PYY), and pancreatic polypeptide (PP) constitute a trio of structurally related peptides that elicit a variety of physiological responses in targets including the brain, gut, and vascular smooth muscle. These actions are mediated by a family of G protein-coupled receptors, each of which exhibits a distinct pharmacological fingerprint. This unit describes protocols for identifying and characterizing the pharmacological properties of two NPY receptor subtypes, Y1 and Y2. At least four other members of this receptor family have been described (Y3, Y4, Y5 and y6), and a brief description of these receptors and relevant literature citations are also provided.
