Summaries for SLC1A3 Gene

Entrez Gene Summary for SLC1A3 Gene

  • This gene encodes a member of a member of a high affinity glutamate transporter family. This gene functions in the termination of excitatory neurotransmission in central nervous system. Mutations are associated with episodic ataxia, Type 6. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2014]

GeneCards Summary for SLC1A3 Gene

SLC1A3 (Solute Carrier Family 1 (Glial High Affinity Glutamate Transporter), Member 3) is a Protein Coding gene. Diseases associated with SLC1A3 include episodic ataxia, type 6 and brain injury. Among its related pathways are SIDS Susceptibility Pathways and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include L-glutamate transmembrane transporter activity and sodium:dicarboxylate symporter activity. An important paralog of this gene is SLC1A6.

UniProtKB/Swiss-Prot for SLC1A3 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 SLC1A3 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.
