nkd is a TFIID-dependent gene in S2R+ cells. (A) TFIID dependence of nkd was determined by depleting the indicated subunits by RNAi and analyzing nkd expression by qRT-PCR. (B) Three different dsRNAs targeting different regions of TAF4 reduced the level of nkd activation. (C) Armadillo stabilization was not affected by TAF4 depletion. Each dsRNA directed against TAF4 was able to efficiently deplete TAF4 levels as determined by α-TAF4 immunoblotting. β-tubulin served as a loading control.
