Protein attributes

Sequence length	444 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

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. Ref.2
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Pancreas and brain. Also expressed in the gastrointestinal system and vagus nerve. Ref.2
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
