Jul 4, 2024 · Here we report that lactate-driven lactylation of NBS1 promotes homologous recombination (HR)-mediated DNA repair. Lactylation of NBS1 at lysine 388 (K388) is essential for MRE11-RAD50-NBS1 (MRN) complex formation and the accumulation of HR repair proteins at the sites of DNA double-strand breaks.

NBS1 dePARylation by NUDT16 is critical for DNA double
Oct 23, 2024 · NBS1, a protein linked to the autosomal recessive disorder Nijmegen breakage syndrome, plays an essential role in the DNA damage response and DNA repair. Despite its importance, the mechanisms regulating NBS1 and the impact of this regulation on DNA repair processes remain obscure.
