Homozygous eye discs show severe defects in hydroxyurea-induced G2 arrest, with the number of mitotic cells remaining high after treatment, in contrast to wild type.
The mitotic checkpoint normally induced by 4000rad of irradiation is not detectable in grp209/grpZ5170 mutants. No checkpoint is detectable in these animals after irradiation with 500rad.
grp209/grpZ5170 males in which excision of insertions of P{hswa} is induced during development are completely viable.
grpZ5170 has chemical sensitive phenotype, enhanceable by lok30
E(mus304)[+]/PolA1Emus304, grp209/grpZ5170 has visible | male limited phenotype
E(mus304)[+]/PolA1Emus304, grp209/grpZ5170 has eye | male limited phenotype
grp209/grpZ5170 ; DNApol-α180Emus304/+ males have a rough eye phenotype, while grp209/grpZ5170 ; DNApol-α180Emus304/+ females have wild-type eyes. The wing discs of these mutant animals show an increase in apoptosis compared to wild type.
