mGluR1 G-protein coupled receptor for glutamate. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Signaling activates a phosphatidylinositol-calcium second messenger system. May participate in the central action of glutamate in the CNS, such as long-term potentiation in the hippocampus and long-term depression in the cerebellum. Belongs to the G-protein coupled receptor 3 family. Detected in brain. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
