HighlightsIntroduction of CCKAR
Cholecystokinin (CCK) is a peptide hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein. CCK binds with high affinity to CCKAR, a seven-transmembrane domain G protein-coupled receptor expressed in pancreatic acinar cells, gallbladder, smooth muscle, chief and D cells of the gastric mucosa, and the central and peripheral nervous systems. Activation of CCKAR stimulates multiple interacting signaling cascades initiated through the Gq family, G13, Gs, and arrestin. The genes of CCKAR consist of five exons interrupted by four introns. Structurally, the extracellular domain of this protein, which adopts a tertiary structure consisting of a few helical turns and a disulfide-cross linked loop, is critical for interactions with its corresponding ligands.

Functions of CCKAR Membrane Protein
Upon binding to this ligand, CCKAR mediates various physiological processes, including pancreatic growth and enzyme secretion, smooth muscle contraction of the gallbladder and stomach, and secretion from gastric mucosal cells in the gastrointestinal system. In the central and peripheral nervous system, this receptor regulates satiety and the release of beta-endorphin and dopamine. OLETF rats have been established as a useful experimental model for examining the biological functions of the CCKAR because of its natural lack of this receptor. Specifically, CCKAR has been shown to be overexpressed in human pancreatic ductal adenocarcinomas (PDAC) and was proposed to be a promising therapeutic approach for treating pancreatic cancer in a gene therapy setting. Besides, genetic variation in this receptor may be implicated in schizophrenia and may also modulate language lateralization due to its impact on dopaminergic pathways. In addition, studies have reported the association of CCKAR polymorphisms with gallbladder diseases.
