UAS regulatory sequences drive expression of a C-terminally truncated form of smo (that ends at residue S939) which is tagged with Tag:FLAG.
smoΔC4.UAS.Tag:FLAG/Scer\GAL4unspecified rescues smounspecified
Expression of smoΔC4.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4unspecified restores naked cuticle in embryos which lack both maternal and zygotic smo function.
