This carrier protein is part of the Na(+)-dependent, binding-protein-independent glutamate-aspartate transport system. Homotrimer. Interacts with FloT (PubMed:23651456). Present in detergent-resistant membrane (DRM) fractions that may be equivalent to eukaryotic membrane rafts; these rafts include proteins involved in signaling, molecule trafficking and protein secretion. Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family.
