Previous GeneCards Identifiers for GRM3 Gene
L-glutamate is the major excitatory neurotransmitter in the central nervous system and activates both ionotropic and metabotropic glutamate receptors. Glutamatergic neurotransmission is involved in most aspects of normal brain function and can be perturbed in many neuropathologic conditions. The metabotropic glutamate receptors are a family of G protein-coupled receptors, that have been divided into 3 groups on the basis of sequence homology, putative signal transduction mechanisms, and pharmacologic properties. Group I includes GRM1 and GRM5 and these receptors have been shown to activate phospholipase C. Group II includes GRM2 and GRM3 while Group III includes GRM4, GRM6, GRM7 and GRM8. Group II and III receptors are linked to the inhibition of the cyclic AMP cascade but differ in their agonist selectivities. [provided by RefSeq, Jul 2008]
GeneCards Summary for GRM3 Gene
GRM3 (Glutamate Metabotropic Receptor 3) is a Protein Coding gene. Diseases associated with GRM3 include Schizophrenia and Bipolar Disorder. Among its related pathways are Circadian entrainment and GPCRs, Class C Metabotropic glutamate, pheromone. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and glutamate receptor activity. An important paralog of this gene is GRM2.
UniProtKB/Swiss-Prot for GRM3 Gene
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 inhibits adenylate cyclase activity.
Metabotropic Glutamate (mGlu) group II receptors are members of the metabotropic class of glutamate receptors, which also includes mGlu group I and mGlu group III receptors. Group II receptors are divided into two subtypes, mGlu2 and mGlu3.
