UASt regulatory sequences drive expression of a mutated form of vvl with a single amino acid substitution within α helix 2 of the POU-specific domain.
decreased cell number | adult stage, with Scer\GAL4Ser.PGF
visible, with Scer\GAL4Ser.PGF
wing, with Scer\GAL4Ser.PGF
Flies expressing vvlB157.Scer\UAS under the control of Scer\GAL4Ser.PGF show striking defects in cell proliferation manifested as a severely notched wing in which cells from within the Scer\GAL4Ser.PGF expression domain are absent.
