Cover Story: Post-translational modifications are critical in the regulation of the DNA damage response. Histone methyltransferase SETD8 regulates the recruitment of 53BP1, a crucial component of DNA double-strand break signaling and repair, to sites of DNA lesions by controlling histone H4K20 methylation. SETD8 levels are tightly regulated during the cell cycle by ubiquitin-dependent proteasomal degradation. This study reports the regulation of SETD8 protein levels by the ubiquitin hydrolase USP29. Wild-type USP29 binds and deubiquitinates SETD8 in vivo. Importantly, USP29 depletion prevents irradiation-induced H4K20 monomethylation and 53BP1 focus formation in addition to increasing cellular sensitivity to irradiation. This study highlights the importance of USP29 for genome stability and cell survival, likely by controlling the protein levels of SETD8.
