| Research Abstract |
Chromosome condensation and segregation are essential phenomena for precise transmission of genome information from mother to daughter cells. In this study, we showed that the condensin complex, which is necessary for chromosome segregation, has continuous role on chromosomes throughout mitosis. Condensin is modified (phosphorylated) during mitosis, but the modification is removed when cells exit from mitosis to next phase (interphase). These results suggest that continuous role of condensin throughout mitosis and its modification changes are important for the stable transmission of genome information and progression of mitotic cells to next cell cycle.
