UASt regulatory sequences drive expression of an inverted repeat.
The expression of Dlg5KK104086 under the control of Scer\GAL4Mef2.PR leads to complete indirect flight muscle atrophy during pupal development (after 32h APF); fibers are longer than in controls and fail to compact at 32h APF.
Expression of CG6509KK104086 under the control of Scer\GAL4c306 results in incomplete border cell migration in some stage 10 egg chambers.
