Investigation of amino acid sequence homology in the protein S100 family via sequence alignment (S100A7: polar bear, Brandt’s bat, Chinese tree shrew, black flying fox, David’s myotis, human, cow, and horse; S100A8: human, cow, mouse, and rat; S100A9: human, cow, rabbit, mouse, and rat). Three regions highlighted in yellow exhibit high homology (a, b, c). “*” indicates complete amino acid identity among all specimens. “:” indicates high amino acid homology. “.” indicates low amino acid homology. Fifty-eight peptides (9 residues each) were selected from highly homologous regions (a, b, c), using the amino acid sequences of human S100A7, S100A8, and S100A9 (Appendix Table 1).
