Abstract:Non-homologous end joining (NHEJ) is the predominant path-way that repairs DNA double-stranded breaks (DSBs) in vertebrates. The DNA termini of many DSBs must be processed to allow ligation while minimizing genetic changes that result from break repair. Emerging models propose that DNA termini are first synapsed approximately 115Å apart in one of two long-range synaptic complexes. The first long-range complex can be formed with only the KU70/80 heterodimer and DNA-PKcs while the second long-range complex also … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
