Analysis of DEFB127 evolution. a) Alignment of predicted amino acid sequences of primate DEFB127 proteins, together with the putative orthologue in dog and cow. Site 71 is highlighted. b) Phylogeny of the DEFB127 gene, with branch sites from the species phylogeny (see Methods) and branch lengths generated from the DEFB127 nucleotide data by maximum-likelihood. Branches showing codon changes corresponding to amino acid changes at site 71 are highlighted.
