Fig. 3. Modulation of DLin-7 protein levels in wing imaginal discs by means of the GAL4/UAS-system. (A) ptc-Gal4-driven overexpression of Flag-DLin-7 strikingly increases Flag-DLin-7 protein levels. (B) Upon overexpression of DLin-7-ds-RNA with ptc-Gal4 the amount of DLin-7 protein is significantly reduced.
