| Research Abstract |
We investigated the molecular mechanisms how initiation of DNA replication is regulated by cell cycle and chromatin structures using model organism fission yeast. We found that phosphorylations of multiple replication factors, Sld3 and Drc1, by cell cycle master kinase CDK are crucial to trigger assembly of replication factors at replication origins. We further discovered the role of Mcm10 after assembly of replication factors to initiate actual DNA synthesis. In approach to elucidate the replication timing program, we discovered that telomere-repeat sequence is located near the late-replicating origins and the telomere-binding proteins are involved in replication timing program. These findings are published on high-quality international journals.
