Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
mus308D5/Df(3R)Exel6166 larvae are unable to survive exposure to 0.005% mechlorethamine (nitrogen mustard).
mus308D5/Df(3R)Exel6166 animals are able to survive exposures of as high as 4000rads of ionising radiation.
Studies of excision and repair events of P{hswa} in mus308D5/mus308Sz29 males indicate that DNA repair synthesis during synthesis-dependent strand annealing (SDSA) is unaffected in the mutants but that the mutants are defective in end-joining repair of DNA double-strand breaks. There is a substantial increase in the percentage of deletion-associated repair events isolated from mus308D5 mutant males relative to those isolated from wild-type males.
PolQD5 is an enhancer of radiation sensitive phenotype of spn-A3
PolQD5/PolQD2, spn-A093A/spn-A3 has partially lethal phenotype
spn-A3 mus308D5 double mutant animals are extremely sensitive to ionising radiation, with almost no survival of the mutants after exposure to 125rads ionising radiation.
There is a decrease in the percentage of end-joining repair products in studies of excision and repair events of P{hswa} in spn-A093A mus308D5/spn-A3 mus308ZIII-2003 double mutant males compared to the percentage seen in spn-A single mutants. The double mutants show a substantial increase in the percentage of deletion-associated repair events isolated compared to controls, as occurs in mus308 single mutants. These males show increased sterility.
There is a decrease in the percentage of end-joining repair products in studies of excision and repair events of P{hswa} in spn-A093A mus308D5/spn-A093A mus308ZIII-3294 double mutant males compared to the percentage seen in spn-A single mutants. The double mutants show an increase in the percentage of deletion-associated repair events isolated compared to controls, as occurs in mus308 single mutants. These males show increased sterility.
mus308D1/mus308D5 has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males, but shows a significant enhancement of meiotic drive in these flies compared to controls.
