Characterization of a Secretory Annexin in Echinococcus granulosus.

In this study, we cloned and characterized Eg-ANX. In silico analysis showed that the amino acid sequence of Eg-ANX was conserved and lacked any signal peptides. The phospholipid-binding activity of recombinant Eg-ANX (rEg-ANX) was tested; liposomes could bind to rEg-ANX only in the presence of Ca(2+). In addition, we performed western blotting and immunohistochemical analyses to further validate the secretory properties of Eg-ANX. The protein could be detected in the cyst fluid of E. granulosus and was also present in the intermediate host tissues, which suggested that Eg-ANX might play an important role in parasite-host interaction.
