DNA-PK driven nucleosome unwrapping enables NHEJ in chromatin

DNA double-strand breaks, one of the most cytotoxic forms of DNA damage, are primarily repaired by non-homologous end joining (NHEJ) in human cells. NHEJ is initiated by the Ku70/80 heterodimer (Ku) and DNA-dependent protein kinase catalytic subunit (DNA-PKcs), followed by factors that bridge and ligate DNA ends. Ku...
