This gene encodes a G-protein coupled receptor for gastrin and cholecystokinin (CCK), regulatory peptides of the brain and gastrointestinal tract. This protein is a type B gastrin receptor, which has a high affinity for both sulfated and nonsulfated CCK analogs and is found principally in the central nervous system and the gastrointestinal tract. A misspliced transcript variant including an intron has been observed in cells from colorectal and pancreatic tumors. [provided by RefSeq, Jul 2008]
GeneCards Summary for CCKBR Gene
CCKBR (Cholecystokinin B Receptor) is a Protein Coding gene. Diseases associated with CCKBR include duodenal gastrinoma and agoraphobia. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include phosphatidylinositol phospholipase C activity and cholecystokinin receptor activity. An important paralog of this gene is GPR19.
UniProtKB/Swiss-Prot for CCKBR Gene
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
Isoform 2 is constitutively activated and may regulate cancer cell proliferation via a gastrin-independent mechanism
The cholecystokinin2 receptor (CCK1 receptor, CCK-B receptor) is a member of the cholecystokinin receptor group of G-protein-coupled receptors that also includes CCK1. They are located primarily in the brain, spinal cord and stomach where they play a role in anxiety, nociception, neuroleptic activity, gastric acid release, gastric mucosal cell growth and histamine release. The human CCK2 receptor gene has been localized to chromosome 11 (11p15.4).
