G-protein coupled receptor for glucagon-like peptide 1 (GLP-1) (PubMed:9568699). Ligand binding triggers activation of a signaling cascade that leads to the activation of adenylyl cyclase and increased intracellular cAMP levels (By similarity). Plays a role in regulating insulin secretion in response to GLP-1 (PubMed:9568699). May form homodimers and heterodimers with GIPR. Detected in pancreatic islets (at protein level). Detected in pancreatic islets and lungs. N-glycosylation enhances cell surface expression and lengthens receptor half-life by preventing degradation in the ER. Belongs to the G-protein coupled receptor 2 family.
