Expression of the Psc coding region (corresponding to amino acids 1-1602) fused at the N-terminal to Tag:FLAG is driven by an 854bp Pc promoter.
PscTag:FLAG partially rescues Psce24
PscTag:FLAG partially rescues Psch27
Psch27/Psce24 embryos rescued by one copy of P{Pc-Psc.FLAG} show rescued denticle belts and some hatch to larvae, though none reach adulthood.
