Cell cycle and Mitosis

The embryonic development of and the maintenance of healthy adult of a eukaryotic organism depends on faithful mitosis. During mitosis, the duplicated genetic materials were transmitted into two daughter cells. Errors in mitosis will lead to aneuploidy daughter cells, and will promote tumorgenesis and other diseases. The morphology and structure of cells changed sharply during mitosis, although the time span of mitosis is short comparing to the whole cell cycle. The course of mitosis is highly dynamic and is under the fine regulation of mitotic kinases (e.g. CDK1, PLK1, Aurora A/B), protein phosphotase and Ubiquitin E3 ligase APC/C. The spindle assembly checkpoint (SAC) is a surveillance mechanism to safeguard the faithful chromosome segregation. Until all chromosomes achieved correct kinetochore-microtubule attachment, the cells enter anaphase due to the satisfaction of SAC. We are interested on the following scientific questions:

1. The molecular composition, assembly, structure and function of kinetochore;
2. The establishment of stable kinetochore-microtubule attachment;
3. Functions and regulations of mitotic kinases;
4. Functions and regulations of motor protein involved in mitosis;
5. The signaling pathway and molecular mechanism of SAC.
