Abstract excerpt
In Saccharomyces cerevisiae, the linker histone HHO1 is involved in DNA repair. In higher eukaryotes, multiple variants of linker histone H1 exist but their involvement in the DNA damage response is unknown. To address this issue, we examined sensitivity to genotoxic agents in chicken DT40 cells lacking specific H1 variants. Among the six H1 variant mutants, only H1R(-/-) DT40 cells exhibited increased...
