UASt regulatory sequences drive expression of an inverted repeat.
Expression of U2af50GD13809 under the control of Scer\GAL4Bx-MS1096 results in wing blisters accommpanied by 'stump' wings.
Expression under the control of Scer\GAL41407 results in loss of neuroblasts in the larval brain associated with increased size of the remaining neuroblasts.
Expression under the control of Scer\GAL41407 results in shorter neuroblast lineages (less daughter cells per neuroblast) in the larval brain compared to controls.
Expression under the control of Scer\GAL41407 results in mild defects in the shape of neuroblasts in the larval brain.
Expression under the control of Scer\GAL4Mef2.PR results in early pupal lethality.
