CC -!- FUNCTION: Transports L-glutamate and also L- and D-aspartate. Essential
CC for terminating the postsynaptic action of glutamate by rapidly
CC removing released glutamate from the synaptic cleft. Acts as a symport
CC by cotransporting sodium (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=a; Synonyms=Glt-2;
CC IsoId=Q10901-1; Sequence=Displayed;
CC Name=b; Synonyms=Glt-1;
CC IsoId=Q10901-2; Sequence=VSP_006267;
CC -!- SIMILARITY: Belongs to the dicarboxylate/amino acid:cation symporter
CC (DAACS) (TC 2.A.23) family. {ECO:0000305}.
