Comparison of amino acid sequences of marine invertebrate and mammalian GAT-1.

Human GAT-1 (HsGAT-1), ratGAT-1 (RnGAT-1), B. septemdierum GAT-1 (BsGAT1), and E. superba GAT-1 (EsGAT1) were compared. Identical amino acids are indicated by asterisks; conservative substitutions are indicated by a single dot; putative transmembrane domains (I-XII) are shaded; red boxes indicate position of amino acids known to be important for the functions of RnGAT-1.
