Domain structure and phylogenetic tree of tick Argonaute-2 proteins. (a) The structure of the predicted Argonaute-2 proteins from I. scapularis and R. microplus in comparison to the structure of Argonaute-2 in D. melanogaster. The predicted structural property of both tick Argonaute-2 candidates is similar to the structure of the fruit fly Argonaute-2 protein. No R. microplus ORF with a Piwi domain similar to Argonaute-2 Piwi was identified. (b) Phylogenetic analysis of Argonaute-2 proteins (Bos = B. taurus, Cat = R. microplus, Cele = C. elegans, Dmel = D. melanogaster, Iscap = I. scapularis, Tcas = T. castaneum).
