UASt regulatory sequences drive expression of an inverted repeat.
Expression of veliGD4647 under the control of Scer\GAL4c306 results in incomplete border cell migration in approximately 50% of stage 10 egg chambers.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 30-40% or 60-70% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 20-30% or 40-50% of the Scer\GAL4pnr-MD237-expressing area of the notum, depending on the insertion line used.
