Entrez Gene Summary for GRM2 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for GRM2 Gene

GRM2 (Glutamate Receptor, Metabotropic 2) is a Protein Coding gene. Diseases associated with GRM2 include schizophrenia. Among its related pathways are Signaling by GPCR and CREB Pathway. GO annotations related to this gene include G-protein coupled receptor activity and glutamate receptor activity. An important paralog of this gene is GRM1.

UniProtKB/Swiss-Prot for GRM2 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, such as adenylate cyclase. Signaling inhibits adenylate cyclase activity. May mediate suppression of neurotransmission or may be involved in synaptogenesis or synaptic stabilization.

Tocris Summary for GRM2 Gene

  • 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. mGlu group II receptors are coupled to Gi/o which inhibits adenylyl cyclase, decreasing the formation of cAMP. mGlu group II receptors are involved in presynaptic inhibition and do not appear to affect postsynaptic membrane potential by themselves. The human genes for mGlu2 and mGlu3 receptors have been localized to chromosomes 3 (p21.1) and 7 (7q21.1-q21.2) respectively.
