This gene encodes a member of the ligand-gated ion channel protein family. The encoded protein is a member of the glycine receptor subfamily. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]
GeneCards Summary for GLRA3 Gene
GLRA3 (Glycine Receptor Alpha 3) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors and Ion channel transport. GO annotations related to this gene include extracellular ligand-gated ion channel activity and extracellular-glycine-gated chloride channel activity. An important paralog of this gene is GLRA1.
UniProtKB/Swiss-Prot for GLRA3 Gene
Glycine receptors are ligand-gated chloride channels. Channel opening is triggered by extracellular glycine (PubMed:9677400, PubMed:26416729). Channel characteristics depend on the subunit composition; heteropentameric channels display faster channel closure (By similarity). Plays an important role in the down-regulation of neuronal excitability (By similarity). Contributes to the generation of inhibitory postsynaptic currents (By similarity). Contributes to increased pain perception in response to increased prostaglandin E2 levels (By similarity). Plays a role in cellular responses to ethanol (By similarity).
Glycine receptors (GlyR) are members of the cys-loop family of ligand-gated ion channels, responsible for mediating the inhibitory effects of glycine. They are widely distributed throughout the CNS, particularly within the hippocampus, spinal cord and brain stem.
