Figure 2From: Selection on MHC class II supertypes in the New Zealand endemic Hochstetter’s frogAmino acid alignment of MHC class II-DAB alleles characterized in Leiopelma hochstetteri. Positively selected sites identified by at least two models (SLAC/REL/MEME; see Methods), shaded in grey; putative peptide binding sites predicted in Xenopus laevis [37] boxed in black outline.Back to article page
