A gene encoding an alpha-tubulin of Cryptosporidium parvum was isolated and
characterized. It had no introns, and encoded a 441-amino acid protein who
se predicted ORF represented a typical alpha-tubulin protein with a MW of 5
0.5 kDa. This tubulin had an amino acid sequence similarity with Apicomplex
a Plasmodium falciparum and Toxoplasma gondii higher than 88% and shared a
number of conserved motifs.
