UASt regulatory sequences drive expression of an inverted repeat.
wing, with Scer\GAL469B
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 pupal cuticle molting defects and interferes with normal wing extension.
Scer\GAL469B-mediated expression results in large epidermal lesions at wounded sites of first instar and immediate lethality.
Scer\GAL469B-mediated expression results in disruption of the epidermal cuticle-ECM and the appearance of large blister-like cuticle extensions in third instars.
