UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4Mef2.PR results in late larval lethality.
Expression under the control of Scer\GAL4pnr-MD237 results in planar polarity defects in the orientation of bristles of the notum in 20-30% of the Scer\GAL4pnr-MD237 expression domain.
