UASt regulatory sequences drive expression of a 500bp inverted repeat.
When expression of rkNIG.8930R is driven by Scer\GAL4Toll-6-D42, flies do not have reduced survival or wing expansion defects. When expression of rkNIG.8930R is driven by Scer\GAL4ap-md544, Scer\GAL4Mef2.PR or Scer\GAL4Act88F.1.3, there is partial lethality (around 20% survive) and escapers have wing defects (100%, 60%, 100%).
