UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL41407 results in shorter neuroblast lineages (less daughter cells per neuroblast) in the larval brain compared to controls.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in early pupal lethality or late pupal lethality.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 100% or 60-70% of the Scer\GAL4pnr-MD237-expressing area of the notum, depending on the insertion line used.
