53BP1 is essential for the repair of DSBs rejoined with slow kinetics in G1 and G2 phase. This 53BP1 function requires its tandem BRCT domain and interaction with NBS1. As a distinct function, 53BP1 suppresses resection during both HR and Artemis and resection-dependent c-NHEJ. This latter role requires RIF1 and is counteracted by BRCA1. 53BP1 appears to be dispensable for the rejoining of the fast c-NHEJ repair process.With the publication of the first paper describing the biochemical properties of DNA polymerase iota (polɩ),
