Role of GW182 domains in silencing. (A–F) S2 cells were treated with dsRNA targeting the 5′- and 3′-UTRs of GW182 mRNA. Control cells were treated with GFP dsRNA. These cells were subsequently transfected with a mixture of three plasmids: one expressing the indicated F-Luc reporters; another expressing miR-12 primary transcripts (+miR-12) or the corresponding empty vector (−); and a third expressing Renilla luciferase (R-Luc). Plasmids (25 ng) encoding wild-type HA-GW182, HA-GW182 mutants, or HA-MBP were included in the transfection mixtures, as indicated. Firefly luciferase activities were normalized to those of the Renilla luciferase transfection control and analyzed as described in Figure 2.
