Previous GeneCards Identifiers 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. Improper regulation of this gene is thought to be associated with several neurological disorders. Alternatively spliced transcript variants of this gene have been identified.

GeneCards Summary for SLC1A2 Gene
SLC1A2 (Solute Carrier Family 1 Member 2) is a Protein Coding gene. Diseases associated with SLC1A2 include Epileptic Encephalopathy, Early Infantile, 41 and Wernicke Encephalopathy. Among its related pathways are Circadian entrainment 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 glutamate:sodium symporter activity. An important paralog of this gene is SLC1A1.
UniProtKB/Swiss-Prot for SLC1A2 Gene
Sodium-dependent, high-affinity amino acid transporter that mediates the uptake of L-glutamate and also L-aspartate and D-aspartate (PubMed:7521911, PubMed:14506254, PubMed:15265858, PubMed:26690923). Functions as a symporter that transports one amino acid molecule together with two or three Na(+) ions and one proton, in parallel with the counter-transport of one K(+) ion (PubMed:14506254). Mediates Cl(-) flux that is not coupled to amino acid transport; this avoids the accumulation of negative charges due to aspartate and Na(+) symport (PubMed:14506254). Essential for the rapid removal of released glutamate from the synaptic cleft, and for terminating the postsynaptic action of glutamate (By similarity).
Glutamate transporters, also known as excitatory amino acid transporters (EAATs), are sodium- and potassium-dependent members of the solute carrier family 6 (SLC1), widely distributed throughout the brain. There are five EAAT subtypes, each with a specific distribution.
