Expression of grhScer\UAS.cKa under the control of Scer\GAL4Act5C.PU, Scer\GAL4da.G32 or Scer\GAL4arm.PS results in lethality at the embryonic or larval stages.
Flies expressing grhScer\UAS.cKa in the epidermis under the control of Scer\GAL4e22c survive to adulthood.
Scer\GAL4e22c/grhUAS.cKa partially rescues grhIM
Expression of grhScer\UAS.cKa in the epidermis under the control of Scer\GAL4e22c partially rescues the cuticle and head skeleton defects seen in grhIM embryos.
Expression of grhScer\UAS.cKa in the epidermis under the control of Scer\GAL4e22c rescues the defects in epidermal barrier integrity seen in stage 17 grhIM homozygous embryos. Epidermal barrier regeneration following wounding is also rescued.
