function:Receptor for gastrin releasing peptide (GRP). This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.,similarity:Belongs to the G-protein coupled receptor 1 family.,tissue specificity:Highly expressed in pancreas. Also expressed in stomach, adrenal cortex and brain.,
Cell membrane ; Multi-pass membrane protein .
Highly expressed in pancreas (PubMed:11245983). Also expressed in stomach, adrenal cortex and brain (PubMed:11245983). In brain, expressed in cells throughout the cortex (PubMed:34610277).
