Receptor for neuropeptide Y (NPY) and peptide YY (PYY) (PubMed:7592910, PubMed:7559383, PubMed:35507650, PubMed:36525977, PubMed:38882210). Can also bind with lower affinity pancreatic polypeptide (PP/PPY) and [Leu-31, Pro-34]NPY, an analog of NPY modified at residues 31 and 34 of the mature form. NPY or PYY binding induces adenylate cyclase-inhibiting G protein-coupled receptor signaling, resulting in inhibition of cAMP production (PubMed:7592910, PubMed:7559383, PubMed:35507650, PubMed:38882210). Receptor activation by ligands also leads to an increase of intracellular Ca(2+) levels (PubMed:7559383, PubMed:7592910). Involved in the regulation of colonic antisecretory tone, and colonic contractility (By similarity). As receptor for peptide PYY(3-36) in the arcuate nucleus of the hypothalamus, it is involved in the down-regulation of appetite and food intake (By similarity). {ECO:0000250|UniProtKB:P97295, ECO:0000269|PubMed:35507650, ECO:0000269|PubMed:36525977, ECO:0000269|PubMed:38882210, ECO:0000269|PubMed:7559383, ECO:0000269|PubMed:7592910}. This is the function of NPY2R (neuropeptide Y receptor Y2, ENSG00000185149).
