Alignment of deduced amino acid sequences of the α1 and α2 domains of bat MHC class I loci with human HLA-A for comparison. The shaded residues in the α1 domain correspond to a putative natural killer (NK) receptor-binding region. Other designations: d, cysteines in the α2 domains likely to form intrachain disulphide bonds. Dashes indicate nucleotide identity, dots indicate nucleotide gaps and asterisks indicate stop codons.
