UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL41407 results in an increased number of GFP-positive aggregates within neuroblast lineage cells in the larval brain compared to controls (these aggregates may indicate cell death or a disturbance of internal cellular structures).
Expression under the control of Scer\GAL4Mef2.PR results in late pupal lethality.
