The "Homology Domain"s HD1 and HD2 of lgs are separated by a 150 amino acid stretch of the yeast Gal11 gene and driven by the αTub84B promoter.
lgsHD1.Gal11.HD2.αTub84B partially rescues lgs20F
The addition of lgsHD1.Gal11.HD2.αTub84B fully rescues the patterning and growth of lgs20F mutants. Although some of these animals fail to hatch from their pupal cases, more than 50% hatch.
