Phylogeny of the Slc10a family shows that ortholog genes identified in lamprey and skate are the most primitive members of the ASBT/SLC10A2 subfamily. Phylogeny was inferred using Bayesian MCMC analysis. Posterior probabilities are indicated at nodes. Branch length is expressed as number of expected substitutions per site. Accession numbers of protein sequences used are listed in supplementary Table III.
