Cholecystokinin receptors or CCK receptors are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) or gastrin.[1] There are two different subtypes CCKA and CCKB which are ~50% homologous:[2] Various cholecystokinin antagonists have been developed and are used in research, although the only drug of this class that has been widely marketed to date is the anti-ulcer drug proglumide.

protein gene tissue distribution preferred ligand function
CCKA (CCK1) CCKAR primarily gastrointestinal tract, lesser amounts in the CNS sulfated CCK >> nonsulfated CCK ≈ nonsulfated CCK stimulation of bicarb secretion, gall bladder emptying and inhibiting gut motility
CCKB (CCK2) CCKBR primarily CNS, lesser amounts in the gastrointestinal track gastrin ≈ CCK (receptor does not descriminate between sulfated and nonsulfated peptides) regulation of nociception, anxiety, memory and hunger
