Description

Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.

(Bellen et al., 2011)

A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal phenotype. The P{lacW} construct carries a w+mC mini-white visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue (FBrf0049800).

Comments concerning location

Insertion site previously reported at 2L:4386525..4386625 .

(FlyBase, 2005)

The insertion is reported to remove the last 64 amino acids of Psf2 and map to codon 151/215 of the Psf2 CDS. That maps to codon 149 of the FlyBase R5.56 Psf2 annotation, which uses a downstream translation start. The published coordinate ( 2L:4388852 ) from the same publication is in error as it maps to Tps1.
