DT Family Dicarboxylate/Amino Acid:Cation (Na(+) Or H(+)) Symporter (DAACS) Family ;
Tissue Specificity Detected in brain (PubMed:8218410,PubMed:7521911, PubMed:8123008). Detected at very much lowerlevels in heart, lung, placenta and skeletal muscle(PubMed:7521911, PubMed:8123008). Highly expressed in cerebellum,but also found in frontal cortex, hippocampus and basal ganglia(PubMed:7521911).
Function This sodium-dependent, high-affinity amino acid transporter functions as a symporter and mediates the uptake of L-glutamate and also L-aspartate and D-aspartate. Mediates Cl(-) flux that is not coupled to amino acid transport; this avoids the accumulation of negative charges due to aspartate and Na(+) symport. 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.
Endogenous Substrate(s) Na+; Aspartate
