Neuropeptide Y receptors

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

« Hide More detailed introduction

Neuropeptide Y (NPY) receptors (nomenclature agreed by NC-IUPHAR on Neuropeptide Y Receptors, [15]) are activated by the endogenous peptides NPY (NPY, P01303), NPY 3-36 (NPY, P01303), peptide YY (PYY (PYY, P10082)), PYY-(3-36) (PYY, P10082) and pancreatic polypeptide (PP (PPY, P01298)). The receptor originally identified as the Y3 receptor has been identified as the CXCR4 chemokine recepter (originally named LESTR, [13]). The y6 receptor is a functional gene product in mouse, absent in rat, but contains a frame-shift mutation in primates producing a truncated non-functional gene [11]. Many of the agonists exhibit differing degrees of selectivity dependent on the species examined. For example, the relative potency of PP (PPY, P01298) is greater at the rat Y4 receptor than at the human receptor [7]. In addition, many agonists lack selectivity for individual subtypes, but can exhibit comparable potency against pairs of NPY receptor subtypes, or have not been examined for activity at all subtypes. [125I]-PYY or [125I]-NPY can be used to label Y1, Y2, Y5 and Y6 subtypes non-selectively, while [125I][cPP(1-7), NPY(19-23), Ala31, Aib32, Gln34]hPP may be used to label Y5 receptors preferentially.
