Phylogenetic analysis of OATP1/Oatp1 family (organic anion-transporting polypeptides; gene family SLCO) in vertebrate phyla. The phylogenetic tree was constructed with the maximum likelihood method. Branch support is estimated with the approximate likelihood ratio test. Species abbreviations are as follows. Hs, Homo sapiens; Gg, Gallus gallus; Tg, Taeniopygia guttata; Ac, Anolis carolinensis; Xt, Xenopus tropicalis; Dr, Danio rerio; Tn, Tetraodon nigroviridis; Tr, Takifugu rubripes; Ga, Gastrosteus aculeatus; Ol, Oryzias latipes; Gm, Gadus morhua; Lc, Latimeria chalumnae; Le, Leucoraja erinacea; Pm, Petromyzon marinus; Ci, Ciona intestinalis.
