UASt regulatory sequences drive expression of an inverted repeat.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in viable flies or early pupal lethality.
Expression under the control of Scer\GAL4pnr-MD237 may result in lethality, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 90-100% of the Scer\GAL4pnr-MD237 expression domain.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 20-30% of the Scer\GAL4pnr-MD237-expressing area of the notum.
