Phylogenetic Relationship Analysis of Bile Acid Transporter(-Like) Proteins.

The corresponding amino acid sequences were aligned with the ClustalX program, and an unrooted tree was calculated using TreeView software. Species and gene names are indicated. Cluster A, plants; B, heterotrophic bacteria group I; C, mammalia; D, cyanobacteria; E, heterotrophic bacteria group II. Ctr, cholate transporter; NTCP, Na⁺/taurocholate cotransporting peptide; ISBT, ileal sodium-dependent bile acid transporter.
