Name Cholecystokinin receptor type A
Description Not Available
Synonyms
  1. CCK-A receptor
  2. CCK-AR
  3. CCK1-R
  4. Cholecystokinin-1 receptor
Gene Name CCKAR
Protein Type Receptor
Biological Properties
General Function Involved in G-protein coupled receptor protein signaling pathway
Specific Function 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
