Neuropeptide Y receptors are a class of G-protein coupled receptors which are activated by the closely related peptide hormones neuropeptide Y, peptide YY and pancreatic polypeptide.[1] These receptors are involved in control of a diverse set of behavioral processes including appetite, circadian rhythm, and anxiety.[2][3][4][5][6][7]

Activated neuropeptide receptors release the Gi subunit from the heterotrimeric G protein complex. The Gi subunit in turn inhibits the production of the second messenger cAMP from ATP.


There are five known mammalian neuropeptide Y receptors designated Y1 through Y5.[8] Four neuropeptide Y receptors each encoded by a different gene have been identified in humans, all of which may represent therapeutic targets for obesity and other disorders.[9][10][11]
