Multiple amino-acid sequence alignments. (A) Multiple amino-acid sequence alignment of BF2*1501, BF2*0401, BF2*2101, HLA-A*0201, HLA-A*2402, and H-2Kb mature peptides. The α1, α2, and α3 domains of pMHC-I molecules are shown by three lines. The secondary structure and sequence number are marked above the sequence alignment. (B) Multiple alignment of chicken, human and mouse CD8α mature peptides. The secondary structure and sequence number are marked above the sequence alignment.
