  • Function

    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.
  • Tissue specificity

    Highly expressed in cerebellum, but also found in frontal cortex, hippocampus and basal ganglia.
  • Involvement in disease

    Defects in SLC1A3 are the cause of episodic ataxia type 6 (EA6) [MIM:612656]. EA6 is characterized by episodic ataxia, seizures, migraine and alternating hemiplegia.
  • Sequence similarities

    Belongs to the sodium:dicarboxylate (SDF) symporter (TC 2.A.23) family. SLC1A3 subfamily.

    *UniprotID Expression Tissue Specificity: Detected in brain and cerebellum (PubMed:1279699, PubMed:8387171). Both isoform EAAT1/GLAST-1 and EAAT1/GLAST-1A are expressed in bone and brain (PubMed:11086157). In brain isoform EAAT1/GLAST-1 is highly enriched in the Purkinje cell layer in cerebellum (PubMed:11086157). 

    Minimal cortex defined: minimal cortex brain samples have had a portion of the cortex removed, with 1/3 cortex, cerebellum and other brain components present in the final lysate.
