Sequence alignment of Echinococcus granulosus α₉-tubulin and corresponding sequences from humans and parasites. The symbol “*” denotes the positions of amino acids that have a single, fully conserved amino acid residue; the symbol “:” denotes conservation between groups of amino acids with strongly similar properties; the symbol “.” denotes conservation between groups of amino acids with weakly similar properties; and the symbol “–” denotes gaps inserted to maximize sequence alignment. EgA9, E. granulosus α₉; HuA6, human alpha 6 (119578461); HmA5, H. microstoma alpha 5 (674586714); HcA, H. contortus alpha tubulin (159155); SjA1, S. japonicum alpha 1–3 (226478902); and TgA, T. gondii alpha (161937).
