UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in a colour difference between the central Scer\GAL4pnr-MD237 expression domain of the notum and the surrounding lateral region in 10-20% of the Scer\GAL4pnr-MD237 expression domain.
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.
