Outline of Final Research Achievements

Genomic DNA is constantly damaged by exposure to endogenous metabolic products and exogenous DNA-damaging agents. DNA replication stress caused by DNA damages potentially leads to genomic mutations and genome instabilities. On the other hand, replication stress can be abolished through the DNA-damage tolerance pathway. In this study, we analyzed a regulatory mechanism of DNA damage tolerance. Our findings indicate that dynamics of chromatin and novel factors are important for regulation of the DNA damage tolerance pathway.
