Heterochromatin is the tightly packed form of repetitive DNA, essential for cell viability. Its highly compacted and repetitive nature renders DSB repair a challenging process that cells need to overcome in order to maintain their genome integrity. Developing a highly specific and robust CRISPR/Cas9 system to target pericentric heterochromatin, we showed that DSBs in G1 are positionally stable and repaired by NHEJ. In S/G2, they relocate to the periphery of this domain to be repaired by HR. This relocation process is dependent of resection and RAD51 exclusion from the core domain of heterochromatin. If these breaks fail to relocate, they are repaired within heterochromatin by NHEJ or SSA. On the other hand, DSBs in centromeric heterochromat...
