Summaries for GLRA2 Gene

Entrez Gene Summary for GLRA2 Gene

  • The glycine receptor consists of two subunits, alpha and beta, and acts as a pentamer. The protein encoded by this gene is an alpha subunit and can bind strychnine. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

GeneCards Summary for GLRA2 Gene

GLRA2 (Glycine Receptor, Alpha 2) is a Protein Coding gene. Diseases associated with GLRA2 include dyscalculia and hyperekplexia. Among its related pathways are Ion channel transport and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include glycine binding and transmitter-gated ion channel activity. An important paralog of this gene is GABRR1.

UniProtKB/Swiss-Prot for GLRA2 Gene

  • The glycine receptor is a neurotransmitter-gated ion channel. Binding of glycine to its receptor increases the chloride conductance and thus produces hyperpolarization (inhibition of neuronal firing)

Tocris Summary for GLRA2 Gene

  • 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. Glycine receptors exist as pentameric proteins, homo-oligomers of the alpha isoforms (alpha1, alpha2, alpha3 or alpha4) or hetero-oligomers which also contain the beta-subtype variant (beta1) which is essential for targeting the receptor to the synapse. Glycine receptors contain an integral chloride channel, and have modulatory sites for anesthetics, neurosteroids, cannabinoids and ethanol. Disruption in glycine receptor expression or ion channel function can result in hyperekplexia, a rare neurological disorder.
