Deletion breakpoint within intron 3. The deletion extends distally from the progenitor P{XP}d06938 insertion site in intron 3, removing Xrp1 sequences downstream of the insertion site.
fertile (with Xrp1Exel6181)
viable (with Xrp1Exel6181)
Xrp1Exel6181/Xrp1Exel6182 show significantly higher rates of loss-of-heterozygosity after irradiation compared to control animals. Mutant larval wing discs show apoptosis and cell cycle arrest after irradiation, as occurs in wild-type discs.
