Glutamate transporter homolog

UniProtKB accession:  O59010

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Sodium-dependent, high-affinity amino acid transporter that mediates aspartate uptake (PubMed:17230192, PubMed:17435767, PubMed:19380583, Ref.11). Has only very low glutamate transport activity (PubMed:17230192, PubMed:19380583). Functions as a symporter that transports one amino acid molecule together with two or three Na(+) ions, resulting in electrogenic transport (PubMed:17435767, PubMed:19380583, Ref.11). Na(+) binding enhances the affinity for aspartate (PubMed:19380583, Ref.11). Mediates Cl(-) flux that is not coupled to amino acid transport; this avoids the accumulation of negative charges due to aspartate and Na(+) symport (PubMed:17435767). In contrast to mammalian homologs, transport does not depend on pH or K(+) ions (PubMed:19380583).
