Expression of the ph-p coding region (corresponding to amino acids 1-1589) fused at the N-terminal to Tag:FLAG is driven by an 854bp Pc promoter.
ph-pTag:FLAG partially rescues ph-p505
Embryos carrying a single copy of P{Pc-ph-p.FLAG} show partially restored denticle belts. Some embryos carrying two copies show fully restored denticle belts.
