Fig. 6: The model of the Dcr-2–Loqs-PD complex in the dsRNA-processing cycle.

The stars represent the mature ATP-binding site, with red and hollow representing whether or not ATP or ADP is bound. The sky-blue region in the Platform–PAZ domains is the dsRNA terminal recognition site. Domains shown in transparent mode with a dotted outline are not visible in that state. The triangles in RIIIDs represent the RNase active centre. The red arrows show the translocation direction.
