Neuropeptide Y receptors are a family of receptors belonging to class A G-protein coupled receptors and they are activated by the closely related peptide hormones neuropeptide Y, peptide YY and pancreatic polypeptide.[1] These receptors are involved in the 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.

Only the crystal structure of Y1 in complex with two antagonist is available.[8]


There are five known mammalian neuropeptide Y receptors designated Y1 through Y5.[9] 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.[10][11][12]
