Molecular mechanisms for pre-replication complexes assembly and its implication in chromosomal stability in mammalian cells

Chromosomal DNA, an essential genetic element, should be precisely replicated during cell growth, failure of which leads to cell death or cancer development. In this research project, we have clarified molecular mechanisms by which DNA replicates once and only once during cells dividing into two daughter cells. Especially, we found that Cdt1 protein is strictly regulated by multiple mechanisms, which are essential for precise DNA replication. Base on these findings, we think that Cdt1 would be a novel target of anti-cancer drugs and we are now trying to find out such compounds. In addition, it turned out that such mechanisms for DNA replication also contribute to maintenance of other chromosomal functions.
