dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family

DESCRIPTION

Also known as EAA2_HUMAN, SLC1A2, EAAT2, GLT1. Sodium-dependent, high-affinity amino acid transporter that mediates the uptake of L-glutamate and also L-aspartate and D-aspartate (PubMed:7521911, PubMed:14506254, PubMed:15265858, PubMed:26690923). 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:14506254). 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:14506254). Essential for the rapid removal of released glutamate from the synaptic cleft, and for terminating the postsynaptic action of glutamate (By similarity). Homotrimer (PubMed:15265858, PubMed:15483603, PubMed:26483543). Isoform 3 can oligomerize with isoform 1 (PubMed:20688910). Interacts with AJUBA (By similarity).
