UASp regulatory sequences drive expression of ph-p containing mutations in the ML binding surface (amino acid replacements L1547R and H1552R). The protein is tagged with Tag:FLAG.
wing disc, with Scer\GAL4en.PU
Expression of ph-pL1547R.H1552R.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4en.PU results in grossly abnormal wing discs consistent with tissue overgrowth.
