Previous GeneCards Identifiers for CCKAR Gene
This gene encodes a G-protein coupled receptor that binds non-sulfated members of the cholecystokinin (CCK) family of peptide hormones. This receptor is a major physiologic mediator of pancreatic enzyme secretion and smooth muscle contraction of the gallbladder and stomach. In the central and peripheral nervous system this receptor regulates satiety and the release of beta-endorphin and dopamine. [provided by RefSeq, Jul 2008]
GeneCards Summary for CCKAR Gene
CCKAR (Cholecystokinin A Receptor) is a Protein Coding gene. Diseases associated with CCKAR include Panic Disorder and Functionless Pituitary Adenoma. Among its related pathways are Peptide ligand-binding receptors and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and cholecystokinin receptor activity. An important paralog of this gene is CCKBR.
UniProtKB/Swiss-Prot Summary for CCKAR Gene
Receptor for cholecystokinin. Mediates pancreatic growth and enzyme secretion, smooth muscle contraction of the gall bladder and stomach. Has a 1000-fold higher affinity for CCK rather than for gastrin. It modulates feeding and dopamine-induced behavior in the central and peripheral nervous system. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.
The cholecystokinin1 receptor (CCK1 receptor, CCK-A receptor) is a member of the cholecystokinin receptor group of G-protein-coupled receptors that also includes CCK2. CCK1 receptors play a role in food intake, pancreatic exocrine secretion, gall bladder contractility and GI motility.
