Alignment of human, dog and cat amino acid sequences of BSEP/Bsep ORF. Differences in amino acid pattern relative to the human BSEP sequence are given in black borders. Transmembrane domains were predicted by Yabuuchi et al. [11] for the dog, and are given in red borders for all species. Walker A is given in purple borders, Walker B in green borders and Signature C in yellow borders. The region of highly different amino acid sequences is given in a blue border.
