Description

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

(Bellen et al., 2004)

A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal or sterile 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).

Location 3L:3444140-3444141 determined by FlyBase alignment of dbGSS accession AQ026254 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation revised.

(FlyBase, 2005)

P{lacW}L3659 insertion maps 360bp upstream of the cIF2 initiation codon.Separable from: l(3)L3659L3659.The P{lacW}L3659 insertion is separable from the lethality of the chromosome (which is caused by l(3)L3659L3659).
