UASt regulatory sequences drive expression of an inverted repeat.
The expression of UxtKK102158 under the control of Scer\GAL4ey.PH leads to a deformed eye, as compared to controls; expression under the control of Scer\GAL4elav-C155 leads to the neuromuscular junctions of third instar larval muscles 6/7 exhibiting clustering of terminal boutons, as well as satellite boutons, as compared to controls.
