靶點詳情

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.

1. We concluded that low serum gastrin is related to increased risk of ER(+) BC development. The results also established that CCKBR/ERK/P65 signaling function is generally tumor suppressive in ER(+) BC, indicating therapies should focus on restoring, not inhibiting, CCKBR/ERK/P65 pathway activity.
