Previous GeneCards Identifiers for GRM5 Gene
This gene encodes a member of the G-protein coupled receptor 3 protein family. The encoded protein is a metabatropic glutamate receptor, whose signaling activates a phosphatidylinositol-calcium second messenger system. This protein may be involved in the regulation of neural network activity and synaptic plasticity. Glutamatergic neurotransmission is involved in most aspects of normal brain function and can be perturbed in many neuropathologic conditions. A pseudogene of this gene has been defined on chromosome 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
GeneCards Summary for GRM5 Gene
GRM5 (Glutamate Metabotropic Receptor 5) is a Protein Coding gene. Diseases associated with GRM5 include Fragile X Syndrome and Fragile X-Associated Tremor/Ataxia Syndrome. Among its related pathways are G-Beta Gamma Signaling and Protein-protein interactions at synapses. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and A2A adenosine receptor binding. An important paralog of this gene is GRM1.
UniProtKB/Swiss-Prot Summary for GRM5 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 activates a phosphatidylinositol-calcium second messenger system and generates a calcium-activated chloride current. Plays an important role in the regulation of synaptic plasticity and the modulation of the neural network activity.
Metabotropic glutamate (mGlu) group I receptors are members of the metabotropic class of glutamate receptors, which also includes mGlu group II and mGlu group III receptors. mGlu group I receptors are divided into two subtypes, mGlu1 and mGlu5.
