Relevance 

KMT7 / SETD7 / SET7/9 is a histone methyltransferase responsible for the methylation of histone H3 K4, p53 and TAF10.

This antibody was used to 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.
