Comments concerning this interaction

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey produced by in vitro translation.

piwi Mid domain demonstrated the strongest interaction with Su(var)2-10 SP-RING+CTD domain, but was reduced with the CTD-2 mutation of Su(var)2-10 or mutation of amino acids in the piwi SIM binding site within the MID domain.
