UAS regulatory sequences drive expression of a construct designed to produce a shRNA targeting exon 16. This should result in the depletion of all long Zasp52 isoforms except one containing exon 17 (exon numbering according to FBrf0216438).
Expression of Zasp52dsRNA.ex16.Scer\UAS under the control of Scer\GAL4Mef2.PR (in the presence of Dcr-2Scer\UAS.cDa to enhance RNAi) results in 44% pupal lethality and adults with impaired flight ability.
The indirect flight muscles of adults expressing Zasp52dsRNA.ex16.Scer\UAS under the control of Scer\GAL4Mef2.PR (in the presence of Dcr-2Scer\UAS.cDa to enhance RNAi) occasionally have bent H-zones.
