UASt regulatory sequences drive expression of an inverted repeat.
Flies expressing Spf45GD9411 under the control of Scer\GAL4Act88F.PB have significant defects in flight ability compared to wild type.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 0% or 10-20% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
