Member of large scale dataset(s)

A set of ~800 largely isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Designed to fill gaps in deletion coverage and breakpoint placement; also used to replace older available deficiencies that have not been molecularly mapped.

Genetic mapping information

Breakpoint based on release 3 sequence coordinate from Thibault et al., 2004, Supplementary Table 2 (FBrf0174227) or 3 (FBrf0174228), converted to release 5 coordinate.

Breakpoint from FlyBase's release 5 sequence location of progenitor insertion.

Comments on Cytology

Exelixis, Inc. determined the insertion site of P{XP}d07887 to be at Release 3 genomic coordinate 8566864 on chromosome arm 2R. This corresponds to 50A13 on the Release 3 and 4 genome maps. The predicted position of PBac{RB}Cap-Ge00771 on the Release 4 map is 49F4. Consequently, the cytological breakpoints of Df(2R)BSC273 are predicted to be 49F4;50A13.

Df(2R)BSC273 heterozygotes show an apparently normal temperature preference profile and an apparently normal circadian behavior (i.e. proportion of rhythmicity and circadian period), as compared to wild-type controls.

Dominantly modifies the size of pupae relative to wild-type controls.
