Neuropeptide Y receptors belong G protein-coupled receptor superfamily and comprise various subtypes. There are currently five cloned NPY receptor subtypes in mammals, termed Y1, Y2, Y4, Y5, and Y6. Neuropeptide Y receptors mediate a variety of physiological responses including feeding and vasoconstriction.

Subtypes Y1, Y2, Y4 and Y5 are expressed in humans. They are present mainly in the central and peripheral nervous systems as well as other tissues, such as the cardiovascular system. Their physiologic ligands are the neurotransmitter Neuropeptide Y and the 2 hormones peptide YY (PYY) and pancreatic polypeptide (PP).

Neuropeptide Y and its receptors regulate important biological and pathophysiological functions, such as blood pressure, neuroendocrine secretions, seizures, neuronal excitability and neuroplasticity.
