DT Family Dicarboxylate/Amino Acid:Cation (Na(+) Or H(+)) Symporter (DAACS) Family ;
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. Essential for the rapid removal of released glutamate from the synaptic cleft, and for terminating the postsynaptic action of glutamate.
Endogenous Substrate(s) Na+; Aspartate
