Neuropeptide Y receptors
neuropeptide y receptors
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. These receptors are involved in the control of a diverse set of behavioral processes including appetite, circadian rhythm, and anxiety.   Activated neuropeptide receptors release the G i subunit from the heterotrimeric G protein complex. The G i subunit in turn inhibits the production of the second messenger cAMP from ATP.
