UASt regulatory sequences drive expression of an inverted repeat.
Expression of EndoUKK115483 under the control of Scer\GAL4elav-C155 leads immature adult appearance with various morphological defects (unexpanded wings, unretracted ptilinum, dimpled thorax, misoriented scutellar bristles, soft cuticle) as well as dramatic locomotor defects and marked lack of coordination (flies are unable to walk or stay upright).
