Phylogenetic relationships for TAP subunits from zebrafish and additional vertebrates with divergent lineages. Deduced amino acid sequences were used to construct maximum likelihood trees. For the largely monomorphic non–MHC-linked Abcb9, Tap1, and Tap2t subunits, only the copies encoded by the Zv9 reference genome are shown. Bootstrap values are provided in SI Appendix, Fig. S8. Chromosome locations for zebrafish Tap2 subunits are provided in parentheses, including haplotype associations when applicable. Sequences are provided in Dataset S2.
