UASt regulatory sequences drive expression of an inverted repeat.
Scer\GAL469B-mediated expression results in larval cuticle molting defects - mutants show characteristic double-cuticles of head skeleton and posterior spiracles in the second and third instar larvae.
Scer\GAL469B-mediated expression results in large epidermal lesions at wounded sites of first instar and immediate lethality.
Scer\GAL469B-mediated expression results in a thinned epidermal cuticle-ECM and stratification defects in third instars.
