WebDec 16, 2016 · In a study using mutants that accumulate unprotected breaks at telomeres (structures maintained within HC), it was demonstrated that 53BP1 has a role in increasing chromatin mobility to promote c-NHEJ . Further, Noon et al. demonstrated that IR-generated DSBs in HC are repaired with slower kinetics than DSBs in EC . Specifically, … WebApr 6, 2024 · Mechanistically, we propose that 53BP1 topology is shaped by two processes: (1) chromatin mobility driven by the SLFN5-LINC-microtubule axis and (2) the assembly of 53BP1 oligomers mediated by SLFN5. In mammals, SLFN5 deficiency disrupts the DSB repair topology and impairs non-homologous end joining, telomere fusions, class switch …
