Excitatory amino acid transporter 2 (SLC1A2)

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 three or two Na(+) ions and one proton, in parallel with the counter-transport of one K(+) ion (PubMed:14506254).

Mediates Cl(-) flux that's not coupled to amino acid transport; this avoids the accumulation of negative charges because of 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).
