A gene encoding an α-tubulin of Cryptosporidium parvum was isolated and characterized. It had no introns, and encoded a 441-amino acid protein whose predicted ORF represented a typical α-tubulin protein with a MW of 50.5 kDa. This tubulin had an amino acid sequence similarity with Apicomplexa Plasmodium falciparum and Toxoplasma gondii higher than 88% and shared a number of conserved motifs.
