Ungoing..... CG15252 DT expression depends on Sal? • CG15252-GFP expression in Sal mutant? • Compare CG15252 expression in btl-gal4; UAS-dys and btl-gal4, UAS-sal; UAS-dys • Compare CG15252 expression in btl-gal4; UAS-dys and btl-gal4, UAS-kni; UAS-dys Co-activator or repressor of Dys::Tgo? • Compare enhancer of CG13196 and CG15252, identify potential binding sites (drifter?)
