Data show that vaccinia-related kinase 1 (VRK1) in resting cells plays an important role in the formation of ionizing radiation-induced foci that assemble on the 53BP1 scaffold protein during the DNA damage response.
Blasco et al., Madrid, Spain. In J Cell Biol, 2012
deletion of 53BP1 in TRF1-deficient cells impairs the C-NHEJ repair pathway, decreasing the occurrence of chromosome-type end to end telomere fusions while inducing a persistent DNA damage signal that activates the ATR-dependent DDR and HR repair pathways
