Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
mus308ZIII-3294/Df(3R)Exel6166 larvae are unable to survive exposure to 0.005% mechlorethamine (nitrogen mustard).
mus308ZIII-3294/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 mus308ZIII-3294/mus308Sz29 males indicate that they are specifically defective in end-joining repair of DNA double-strand breaks. There is an increase in the percentage of deletion-associated repair events isolated from mus308ZIII-3294 mutant males relative to those isolated from wild-type males.
Mutant larvae are sensitive to nitrogen mustard (compared to control larvae). Mutant larvae are not sensitive to methyl methanesulfonate.
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.
