This gene encodes a member of the high-affinity glutamate transporters that play an essential role in transporting glutamate across plasma membranes. In brain, these transporters are crucial in terminating the postsynaptic action of the neurotransmitter glutamate, and in maintaining extracellular glutamate concentrations below neurotoxic levels. This transporter also transports aspartate, and mutations in this gene are thought to cause dicarboxylicamino aciduria, also known as glutamate-aspartate transport defect.

GeneCards Summary for SLC1A1 Gene
SLC1A1 (Solute Carrier Family 1 Member 1) is a Protein Coding gene. Diseases associated with SLC1A1 include Dicarboxylic Aminoaciduria and Schizophrenia 18. Among its related pathways are Circadian entrainment and Collagen chain trimerization. Gene Ontology (GO) annotations related to this gene include L-glutamate transmembrane transporter activity and sodium:dicarboxylate symporter activity. An important paralog of this gene is SLC1A3.
UniProtKB/Swiss-Prot for SLC1A1 Gene
Sodium-dependent, high-affinity amino acid transporter that mediates the uptake of L-glutamate and also L-aspartate and D-aspartate (PubMed:7914198, PubMed:7521911, PubMed:8857541, PubMed:26690923, PubMed:21123949). Can also transport L-cysteine (PubMed:21123949). 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:7521911, PubMed:8857541, PubMed:26690923). 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:8857541, PubMed:26690923). Plays an important role in L-glutamate and L-aspartate reabsorption in renal tubuli (PubMed:21123949). Plays a redundant role in the rapid removal of released glutamate from the synaptic cleft, which is essential for terminating the postsynaptic action of glutamate (By similarity). Negatively regulated by ARL6IP5 (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.
