Function
[GASR_HUMAN] Receptor for gastrin and cholecystokinin. The CKK-B receptors occur throughout the central nervous system where they modulate anxiety, analgesia, arousal, and neuroleptic activity. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.[1] [2] [3] [4] [5] [6] Isoform 2 is constitutively activated and may regulate cancer cell proliferation via a gastrin-independent mechanism.[7] [8] [9] [10] [11] [12]
