Expression of dapScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4prd.PU does not interfere with the normal cell cycle program of embryonic epidermal cells or on the endocycle progression of embryonic midgut cells. Scer\GAL4αTub84B.PL-driven expression also has no effect on the proliferation or differentiation of central and peripheral nervous system. dapScer\UAS.P\T.T:Avic\GFP-EGFP expression under the Scer\GAL4en.PU driver does not disrupt growth or proliferation of the imaginal wing disc cells or - with the Scer\GAL4ptc-559.1 driver, the endocycle program in the salivary gland cells in third instar larvae. However, expression under the Scer\GAL4c323 driver does disrupt the endocycle progression in the ovarian follicle cells.
