An intronless gene encoding a protein of 674 amino acid residues with a molecular mass of 73,403 Da showing homology to the cytoplasmic form of the 70 kDa heat shock proteins has been cloned and sequenced from the intestinal pathogen Cryptosporidium parvum. Monospecific polyclonal antibodies obtained to recombinant protein recognized a single band with an approximate molecular mass of 70 kDa on a Western blot of C. parvum proteins, as well as the 70 kDa heat shock protein from bovine brain. Southern blot analysis suggested the gene was single copy in the C. parvum genome. Eleven perfect repeats of the sequence GGMP were found in the predicted protein near the carboxyl terminus.
