Neuropeptide Y receptor

Neuropeptide Y receptors are receptors for Neuropeptide Y. They are all G-protein coupled receptors, coupling to Gi.

Types
There are five known mammalian neuropeptide y receptors designated Y1 through Y5.

Four neuropeptide y receptors each encoded by a different gene have been identified in humans:
 * Y1 -
 * Y2 -
 * Y4 -
 * Y5 -

The neuropeptide Y receptors act as receptors for NPY, PYY and pancreatic polypeptide which are a closely related group of peptides.
