UASt regulatory sequences drive expression of an inverted repeat.
Embryos expressing McrKK104742 under the control of Scer\GAL4btl.PS have elongated trachea compared to wild type.
Embryos expressing McrKK104742 under the control of Scer\GAL4da.PU lack almost all ventral denticle belts and have ectopic deposits in the region of the salivary glands.
Embryos expressing McrKK104742 under the control of Scer\GAL4btl.PS have convoluted trachea.
The wing discs of third instar larvae expressing McrKK104742 under the control of Scer\GAL4ap-md544 have disrupted paracellular barrier function in a dye exclusion assay. In the presence of Dcr-2Scer\UAS.cDa (to enhance RNAi), the discs show disrupted septate junction organisation (assayed by cora protein localisation).
