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
Comments

Deficiency complementation analysis is consistent with the lethality of the line being associated with the insertion. However, since the insertion lies within multiple genes (MED9 and CG42518), the lethality can not yet be conclusively mapped to a single gene from these results. Thus l(2)SH0499SH0499 (representing the lethality of the chromosome) has been kept as a separate allele in FlyBase for now.

Location 2R:13681789-13682146 confirmed by FlyBase alignment of dbGSS accession AB082094 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation confirmed.
