UAS regulatory sequences drive expression of full length pyd-PB cDNA. The protein is tagged with the mRFP1 fluorescent protein.
interommatidial precursor cell | pupal stage
Expression of pydScer\UAS.T:Disc\RFP under the control of Scer\GAL4GMR.PF results in inter-ommatidial precursor cell patterning defects.
