UASp regulatory sequences drive expression of the CTPsyn C isoform synthetase domain which is tagged at the C-terminal end with Venus.
cytoophidium | somatic clone, with Scer\GAL4Tub.PU
Expression of CTPsynSD.Scer\UAS.P\T.C.C.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4tub.PU in follicle cell clones disrupts endogenous cytoophidium formation in the mutant follicle cells.
