A genomic fragment that includes the wild-type mus308 transcription unit plus 1.25kb of upstream sequence.
PolQ+tBa is a suppressor of radiation sensitive | third instar larval stage phenotype of Df(3R)PolQΔ, spn-A093A/spn-A3
The hypersensitivity of Df(3R)mus308Δ/Df(3R)mus308Δ;spn-A3/spn-A093A double mutant third instar larvae to ionizing radiation is rescued by combination with the mus308+tBa. Similarly, the Df(3R)mus308Δ/Df(3R)mus308Δ;spn-A3/spn-A093A mutants show a significant reduction in the frequency of end joining repair events in a P{hsw[a]}-excision repair assay,and this is also rescued with mus308+tBa.
