Fig. 7. Sens can synergize with proneural proteins on the UAS-tk-luc
reporter in S2 cell transcription assays. (A) Schematics of the
UAS-tk-luc reporter construct. (B) S2 cell transcription
assays using UAS-tk-luc reporter. Sens expression alone does not have
a significant effect on the basal expression of the UAS-tk-luc
reporter. However, Sens is able to synergize with Sc and Ac. (C)
E(spl)m7 strongly inhibits the expression induced by the Sc-Gal4DBD and the
synergism between Sens and Sc-Gal4DBD. (D) When fused to Gal4DBD, Sens
acts as a strong repressor on the UAS-tk-luc reporter. Ac and Sc fail
to synergize with DNA-bound Sens.
