Summaries for SLC1A2 Gene

Entrez Gene Summary for SLC1A2 Gene

  • This gene encodes a member of a family of solute transporter proteins. The membrane-bound protein is the principal transporter that clears the excitatory neurotransmitter glutamate from the extracellular space at synapses in the central nervous system. Glutamate clearance is necessary for proper synaptic activation and to prevent neuronal damage from excessive activation of glutamate receptors. Mutations in and decreased expression of this protein are associated with amyotrophic lateral sclerosis. Alternatively spliced transcript variants of this gene have been identified.

GeneCards Summary for SLC1A2 Gene

SLC1A2 (Solute Carrier Family 1 (Glial High Affinity Glutamate Transporter), Member 2) is a Protein Coding gene. Diseases associated with SLC1A2 include brain injury and traumatic brain injury. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Transmission across Chemical Synapses. GO annotations related to this gene include L-glutamate transmembrane transporter activity and glutamate:sodium symporter activity. An important paralog of this gene is SLC1A3.

UniProtKB/Swiss-Prot for SLC1A2 Gene

  • Transports L-glutamate and also L- and D-aspartate. Essential for terminating the postsynaptic action of glutamate by rapidly removing released glutamate from the synaptic cleft. Acts as a symport by cotransporting sodium

Tocris Summary for SLC1A2 Gene

  • Glutamate transporters, also known as excitatory amino acid transporters (EAATs), are sodium- and potassium-dependent members of the solute carrier family 6 (SLC1) found widely distributed throughout the brain. There are five EAAT subtypes, each with a specific primary distribution; EAAT1 (cerebellar glia), EAAT2 (forebrain glia), EAAT3 (cortical neurons), EAAT4 (cerebellar Purkinje neurons) and EAAT5 (retina). Functions of glutamate transporters include regulation of excitatory neurotransmission, maintenance of low ambient extracellular glutamate concentrations (protects against neurotoxicity) and providing glutamate for metabolism through the glutamate-glutamine cycle. Overactivity of glutamate transporters has been implicated in the pathophysiology of schizophrenia and other mental illnesses, whilst underactivity is seen in ischemia and traumatic brain injury.
