UAS regulatory sequences drive expression of the RING finger domain of the Cbl long isoform fused to the SH2 domain of drk (amino acids 53-160), tagged with Tag:FLAG.
Expression of Cbl::drkCblL-RING.drk-SH2.Scer\UAS.T:Zzzz\FLAG suppresses the dorsalised egg shell phenotype observed in animals expressing btl::EgfrScer\UAS.T:λ\cI-DD under the control of Scer\GAL4EQ1.
