UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in semi-lethality (either before or at the pupal stage), depending on the insertion line used.
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 60-70% or 70-80% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
