Mol Biochem Parasitol. 2012;183:94-9 pubmed publisher
    ..Our data strongly suggest a rhoptry localization for the newly characterised protein, which was therefore renamed C. parvum putative rhoptry protein-1 (CpPRP1). ..

    ..The results of this study reveal that the C. parvum SSAT may provide a rational target for drug design. ..
