Histone lysine methylation is a key regulator of gene expression and heterochromatin function, but little is known as to how this modification impinges on other chromatin activities. Here we demonstrate that a previously uncharacterized SET domain protein, Set9, is responsible for H4-K20 methylation in the fission yeast Schizosaccharomyces pombe. Surprisingly, H4-K20 methylation does not have any apparent role in the regulation of gene expression or heterochromatin function. Rather, we find the modification has a role in DNA damage response. Loss of Set9 activity or mutation of H4-K20 markedly impairs cell survival after genotoxic challenge and compromises the ability of cells to maintain checkpoint mediated cell cycle arrest. Genetic experiments link Set9 to Crb2, a homolog of the mammalian checkpoint protein 53BP1, and the enzyme is required for Crb2 localization to sites of DNA damage. These results argue that H4-K20 methylation functions as a "histone mark" required for the recruitment of the checkpoint protein Crb2. << Less
