UAS regulatory sequences drive expression of a chimeric protein that is composed of the extracellular and transmembrane regions of Mmus\Cd8a fused to a portion of the cytoplasmic domain of Egfr (which includes the kinase domain but lacks the C-tail). The protein is tagged at the C-terminal end with GFP.
Expression of EgfrΔC.Scer\UAS.T:Avic\GFP,T:Mmus\Cd8a under the control of Scer\GAL4CY2 in the follicle cells does not result in a mutant chorion phenotype.
