UAS regulatory sequences drive expression of a slmb-binding mutant of Cap-H2, in which two key residues in the binding consensus have been mutated, changing DSGISS to DAGISA (S963A/S967A).
Expression of Cap-H2Scer\UAS.SBM under the control of Scer\GAL4Bx-MS1096 causes no growth or polarity defects in wing discs.
