Entrez Gene Summary for SLC1A1 Gene

  • 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. [provided by RefSeq, Mar 2010]

GeneCards Summary for SLC1A1 Gene

SLC1A1 (Solute Carrier Family 1 (Neuronal/Epithelial High Affinity Glutamate Transporter, System Xag), Member 1) is a Protein Coding gene. Diseases associated with SLC1A1 include dicarboxylic aminoaciduria and schizophrenia susceptibility 18. 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 sodium:dicarboxylate symporter activity. An important paralog of this gene is SLC1A3.

UniProtKB/Swiss-Prot for SLC1A1 Gene

  • Transports L-glutamate, L- and D-aspartate and L-cystein (PubMed:21123949). Essential for terminating the postsynaptic action of glutamate by rapidly removing released glutamate from the synaptic cleft. Acts as a symport by cotransporting sodium. Negatively regulated by ARL6IP5 (By similarity).

Tocris Summary for SLC1A1 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.

Disorders for SLC1A1 Gene

(1) OMIM Diseases for SLC1A1 Gene (133550)


  • Dicarboxylic aminoaciduria (DCBXA) [MIM:222730]: An autosomal recessive disorder characterized by abnormal excretion of urinary glutamate and aspartate, resulting from the incomplete reabsorption of anionic amino acids from the glomerular filtrate in the kidney. It can be associated with mental retardation. {ECO:0000269 PubMed:21123949}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Schizophrenia 18 (SCZD18) [MIM:615232]: A complex, multifactorial psychotic disorder or group of disorders characterized by disturbances in the form and content of thought (e.g. delusions, hallucinations), in mood (e.g. inappropriate affect), in sense of self and relationship to the external world (e.g. loss of ego boundaries, withdrawal), and in behavior (e.g bizarre or apparently purposeless behavior). Although it affects emotions, it is distinguished from mood disorders in which such disturbances are primary. Similarly, there may be mild impairment of cognitive function, and it is distinguished from the dementias in which disturbed cognitive function is considered primary. Some patients manifest schizophrenic as well as bipolar disorder symptoms and are often given the diagnosis of schizoaffective disorder. {ECO:0000269 PubMed:21982423, ECO:0000269 PubMed:23341099}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. A deletion at the chromosome 9p24.2 locus, including SLC1A1, has been identified in patients with psychotic disorders (PubMed:21982423). This 84 kb deletion is immediately upstream of the SLC1A1 gene in a regulatory region that contains the full native promoter sequence, extends through exon 1 of the SLC1A1 mRNA, co-segregates with disease in an extended 5-generation pedigree and increases disease risk more than 18-fold for family members (PubMed:23341099). {ECO:0000269 PubMed:21982423, ECO:0000269 PubMed:23341099}.
