End processing in NHEJ by Polymerase λ and PNKP is coordinated during short-range synapsis

Non-homologous end joining (NHEJ) is a major pathway of DNA double strand break (DSB) repair, capable of directly joining both damaged strands of DNA through the coordinated activities of repair factors that detect the termini, physically bridge them together, and perform the che...

Molecular basis of nick ligation in the nucleosome by DNA Ligase IIIα

Eukaryotic genomic DNA is packaged into chromatin through a fundamental repeating unit known as the nucleosome core particle. Within this chromatin context, genomic DNA is constantly exposed to endogenous and exogenous stress that result in the formation of DNA damage, which must...
