WebThe receptors for gastrin and cholecystokinin (CCK) are related and constitute the “CCK/Gastrin receptor family.”. Two classic types of receptors have been characterized: CCK-A receptor (previously CCK-1R), having affinity mainly for CCK, and CCK-B receptor (previously CCR-2R) which is the main receptor for gastrin. WebCCK is thought to function primarily as a neurotransmitter/hormone/neuromodulator, whereas gastrin functions primarily as a hormone.
