Cholecystokinin receptors
cholecystokinin receptors
Cholecystokinin receptors or CCK receptors are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) or gastrin. There are two different subtypes CCK A and CCK B which are ~50% homologous : 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.
