Deskripsi
rDNA repeats residing in the nucleolus must be released to the nucleoplasm to allow repair by homologous recombination. Here the authors reveal insights into the molecular mechanism proposing that phosphorylation and SUMOylation of the rDNA-tethering complex facilitate the nucleolar release of damaged repeats to maintain genome integrity.
