The Cholecystokinin A receptor is a human protein, also known as CCKAR or CCK₁, with CCK₁ now being the 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 N-terminal domain of this protein adopts a tertiary structure consisting of a few helical turns and a disulfide-cross linked loop. It is required for interaction of the cholecystokinin A receptor with its corresponding hormonal ligand. ^[6]
