lexA::VP16 coding sequence has been inserted at the C-terminal end of the endogenous Egfr coding sequence. The native Egfr 3'UTR is present downstream of the lexA::VP16 sequence, followed by an attP site and a Disc\RFPDsRed(T1).3xP3.cHa marker that were inserted during the mutagenesis event. The chimeric Egfr ::lexA::VP16 protein does not detectably activate reporter expression.
