Structural highlights

Disease

GRM1_HUMAN Autosomal recessive congenital cerebellar ataxia due to MGLUR1 deficiency. The disease is caused by mutations affecting the gene represented in this entry.^[1]

Function

GRM1_HUMAN 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.^[2]
