Research Abstract |
We have clarified the mechanism in which human DNA polymerase η (Polη) interacts with other proteins for switching between Polη and the replicative polymerase at stalled replication forks. We have solved high-resolution crystal structures of human Polη at four consecutive steps during DNA synthesis through cis-syn cyclobutane thymine dimers. In addition, we have generated Polηknockout mice and observed high incidence of skin tumors upon UV-B irradiation in these mice.
