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.
Error in previous genomic location reported in FlyBase ( 2L:12 ,496,810, r5): original sequence location data reported for release 3 genomic sequence; FlyBase error in promotion to subsequent releases.
May have arisen in multiple insertion line: original in situ hybridization data conflict, may correspond to second insertion.
