GRM1 Antibody – Rabbit Polyclonal

mGluR1: Receptor for glutamate. The activity of this receptor is mediated by a G-protein that 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. Homodimer; disulfide-linked. The PPXXF motif binds HOMER1, HOMER2 and HOMER3. Interacts with SIAH1, RYR1, RYR2, ITPR1, SHANK1, SHANK3 and GRASP. Belongs to the G-protein coupled receptor 3 family. 2 isoforms of the human protein are produced by alternative splicing.
