UASt regulatory sequences drive expression of an inverted repeat.
Around 40% of flies with expression of Ufc1KK107529 driven by Scer\GAL4da.PU exhibit abnormal vertical-turned wings that fail to fold, and mutants show significant decreases in climbing ability compared to controls.
Third instar larvae with expression of Ufc1KK107529 driven by Scer\GAL4RapGAP1-OK6 show significant decreases in type Ib bouton number and increases in bouton size at the neuromuscular junction, compared to controls.
