UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in loss of bristles on the notum 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 10-20% of the Scer\GAL4pnr-MD237 expression domain.
