UAS regulatory sequences drive expression of a mutated form of ptc (amino acid replacements T1260P, T1263P, T1265P).
visible, with Scer\GAL4en-e16E
wing, with Scer\GAL4en-e16E
Expression of ptc3P.Scer\UAS under the control of Scer\GAL4en-e16E results in extreme reductions in the central wing region.
