956bp deletion that extends from upstream of the Bap170 transcriptional start site into the second exon, moving the first 213 amino acid residues. This deletion leaves Trap1 and the intergenic region between Trap1 and Bap170 intact, and presumably resulted from a transposition of the P{EPgy2}Trap1EY10238 insertion into the 5'UTR of Bap170, followed by an imprecise excision.
Homozygotes have reduced adult viability (30 to 33% at 25[o}C), but the adult survivors have no morphological defects except for variable ectopic wing vein material.
Bap170Δ65, Su(var)3-3[+]/Su(var)3-3ΔN has visible | dominant phenotype
Bap170Δ65, polybromoΔ86 has lethal | pupal stage phenotype
Bap170Δ65, Su(var)3-3[+]/Su(var)3-3ΔN has wing vein | ectopic phenotype
Bap170Δ65, polybromoΔ86 has ventral denticle belt phenotype
Bap170Δ65, polybromoΔ86 has embryonic/larval crystal cell phenotype
Bap170Δ65, polybromoΔ86 has leg | pupal stage phenotype
Bap170Δ65, polybromoΔ86 has melanotic mass | pupal stage phenotype
Bap170Δ65 polybromoΔ86 double mutants show fully penetrant pupal lethality, which can be rescued by ubiquitous expression of either polybromoScer\UAS.cCa or Bap170Scer\UAS.cCa.
Bap170Δ65 polybromoΔ86 double mutant larvae show overproduction of crystal cells.
Bap170Δ65 polybromoΔ86 double mutants show defects at the pupal stage beginning approximately 12 hours after puparium formation; the mutants fail to fully evert their legs and sometimes have melanotic patches.
Embryos laid by Bap170Δ65 females containing polybromoΔ86 homozygous germ line clones die before the third larval instar. Cuticles secreted by the embryos that fail to hatch show dorsalisation (ventral denticle belts are reduced), especially in the anterior region.
Bap170Δ65 females with osa308 polybromoΔ86 germ lines clones are able to differentiate oocytes.
