Amino acid sequence similarity shown as identical sequence percentage. AtVTI1a, AtVTI1b, and yVti1p, Saccharomyces cerevisiae (accession number 2497184); HVti1p, Homo sapiens (accession number 268740); mVti1a, Mus musculus (accession number 3213227); mVTI1b, Mus musculus (accession number 3213229). The optimal alignments were produced using the J. Hern method in the DNAStar program.
