PBac{PBss} insertion in the third intron.
Homozygous scafPBss escapers exhibit a head scar under the proboscis.
Homozygous adult escapers have what appears to be "scarring" around the mouthparts that is indicative of necrotic tissue.
scafPBss is partially rescued by scafUAS.cRa/Scer\GAL4Act5C.PI
Expression of scafScer\UAS.cRa driven by Scer\GAL4Act5C.PI partially rescues the lethality of homozygousscafPBss mutants.
