  • 功能：
    Receptor for gastrin and cholecystokinin. The CCK-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.; Isoform 2 is constitutively activated and may regulate cancer cell proliferation via a gastrin-independent mechanism.
