Biol. Chem. 269:19573-19577(1994). CC -!- FUNCTION: Transports L-glutamate and also L- and D-aspartate. CC Essential for terminating the postsynaptic action of glutamate by CC rapidly removing released glutamate from the synaptic cleft. Acts CC as a symport by cotransporting sodium. CC -!- SUBUNIT: Homotrimer (By similarity). CC -!- SUBCELLULAR LOCATION: Membrane; multi-pass membrane protein. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=Glt1; CC IsoId=P31596-1; Sequence=Displayed; CC Name=Glt-1A; CC IsoId=P31596-2; Sequence=VSP_006266; CC -!- TISSUE SPECIFICITY: Localized in brain and is highly enriched in CC the Purkinje cell layer in cerebellum. CC -!- PTM: Glycosylated. CC -!- SIMILARITY: Belongs to the sodium:dicarboxylate (SDF) symporter CC (TC 2.A.23) family.
