UAS regulatory sequences drive expression of the long Cbl isoform carrying a modified PPLPPR motif, where the first and fifth prolines are replaced with alanines (APLPAR).
dorsal appendage, with Scer\GAL4EQ1
Expression of CblL.mPR.Scer\UAS in the follicle cells under the control of Scer\GAL4EQ1 results in a ventralised eggshell phenotype. Eggs display disrupted dorsal appendage morphology, and fusing or loss of dorsal appendages is observed.
CblL.mPR.UAS, Scer\GAL4EQ1 has dorsal appendage phenotype, non-suppressible by drk[+]/drke0A/drke0A
drke0A/+ fails to suppresses the ventralised egg shell phenotype observed when CblL.mPR.Scer\UAS is expressed in follicle cells under the control of Scer\GAL4EQ1.
