Alignment of the amino acid sequences of residues 9 to 91 of the first domain of DRB alleles of forest musk deer.
“+” indicates residues in the peptide binding region according to human DRB structure47 and residues highlighted in yellow show positively selected sites. Arrows indicate postulated recombination breakpoints. The major configurations of the protein are shown: β-strand region (REGION I), the major part of α-helical region (REGION II) and the carboxyterminal part of the α-helical region (REGION III).
