V303E
mus302D1 and mus302D1/mus302Z1882 mutants are sensitive to 0.025% MMS.
Excision repair capacity is partly deficient and post-replication repair capacity is deficient.
Mutants exhibit normal photorepair capacity.
Flies are sensitive to X rays.
Hypersensitive to methyl methanesulfonate. Sensitive to 0.008% HN2.
mus302D1/mus302Z1882 has chemical sensitive phenotype, enhanceable by spn-A093A/spn-A3
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.
mus302D1/mus302Z1882 is rescued by mus302+t3.3
Boyd.
Homozygotes have reduced levels of excision and postreplication repair compared to wild-type. Homozygous cultured cells respond to UV irradiation with unusually low thymidine incorporation and with the synthesis of abnormally short nascent DNA.
The recovery of chromosomes undergoing P-element transposition is severely reduced in homozygous mus302D1 and mus302D1/mus302D2 flies, suggesting that mus302+ function is required for the recovery of these chromosomes.
