The Cholecystokinin A receptor is a human

IUPHAR
-recommended name.

Function

This gene encodes a G-protein coupled receptor that binds sulfated members of the cholecystokinin (CCK) family of peptide hormones. This receptor is a major physiologic mediator of pancreatic enzyme secretion and smooth muscle contraction of the gallbladder and stomach. In the central and peripheral nervous system this receptor regulates satiety and the release of beta-endorphin and dopamine.[5]

The extracellular,

disulfide-cross linked loop. It is required for interaction of the cholecystokinin A receptor with its corresponding hormonal ligand.[6]
