EAAT4 is an alias for the gene, Solute carrier family 1 (high affinity aspartate/glutamate transporter), member 6, in humans. Other names include: Excitatory amino acid transporter 4; Solute carrier family 1 member 6; Sodium-dependent glutamate/aspartate transporter. The encoded protein has an amino acid length of 564 and a mass of 61.6 kDa. Other isoforms may exist. EAAT4 is a member of the Sodium:dicarboxylate (SDF) symporter (TC 2.A.23) family, SLC1A6 subfamily. This gene shares homology with other species, including: Mouse, Rat.
