UAS sequences drive expression of a mutated CycB, where the destruction box has been replaced by a pim destruction box. The amino acids GT and RT have also been added as a consequence of the cloning strategy and flank the inserted sequence.
viable | embryonic stage, with Scer\GAL4da.G32
wild-type, with Scer\GAL4prd.RG1
Expression of CycB::pimdbpim.Scer\UAS when driven by Scer\GAL4 does not block mitosis during embryonic development.
