CC -!- FUNCTION: Sodium-dependent, high-affinity amino acid transporter that
CC mediates the uptake of L-glutamate and also L-aspartate and D-aspartate
CC (PubMed:7723632). Functions as a symporter that transports one amino
CC acid molecule together with two or three Na(+) ions and one proton, in
CC parallel with the counter-transport of one K(+) ion (By similarity).
CC Plays a redundant role in the rapid removal of released glutamate from
CC the synaptic cleft, which is essential for terminating the postsynaptic
CC action of glutamate (By similarity). {ECO:0000250|UniProtKB:O57321,

CC -!- SUBUNIT: Homotrimer (By similarity). {ECO:0000250|UniProtKB:P43003}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:7723632};
CC Multi-pass membrane protein.
CC -!- DOMAIN: Contains eight transmembrane regions plus two helical hairpins
CC that dip into the membrane. These helical hairpin structures play an
CC important role in the transport process. The first enters the membrane
CC from the cytoplasmic side, the second one from the extracellular side.
CC During the transport cycle, the regions involved in amino acid
CC transport, and especially the helical hairpins, move vertically by
CC about 15-18 Angstroms, alternating between exposure to the aqueous
CC phase and reinsertion in the lipid bilayer. In contrast, the regions
CC involved in trimerization do not move. {ECO:0000250|UniProtKB:P43003}.
CC -!- PTM: Glycosylated. {ECO:0000250|UniProtKB:P24942}.
CC -!- SIMILARITY: Belongs to the dicarboxylate/amino acid:cation symporter
CC (DAACS) (TC 2.A.23) family. SLC1A3 subfamily. {ECO:0000305}.
