Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.
A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{PZ}; most lines have a lethal or sterile phenotype. The P{PZ} construct carries a ry[+] visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue.
Reported to be 52 bp upstream of the 5' end of longest zfh1 cDNA from FBrf0054606 (GB:M63449)
