Previous GeneCards Identifiers for GRM6 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, Feb 2012]
GeneCards Summary for GRM6 Gene
GRM6 (Glutamate Receptor, Metabotropic 6) is a Protein Coding gene. Diseases associated with GRM6 include autosomal recessive congenital stationary night blindness and night blindness, congenital stationary , 1b, autosomal recessive. 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 GRM6 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 (By similarity). Signaling stimulates TRPM1 channel activity and Ca(2+) uptake. Required for normal vision.
Metabotropic Glutamate (mGlu) group III receptors are members of the metabotropic class of glutamate receptors, which also includes mGlu group I and mGlu group II receptors. Group III receptors are divided into four subtypes, mGlu4, mGlu6, mGlu7 and mGlu8.
