Nonhomologous End Joining in Eukaryotes

Eric - Weterings, D. J. Chen

Research output: Chapter in Book/Report/Conference proceedingChapter


This article discusses the core mechanism of the nonhomologous end-joining (NHEJ) process: one of two pathways that mediate the repair of DNA double-strand breaks (DSBs) in eukaryotic cells. Through complex interplay of several enzymes, NHEJ facilitates the capture, tethering, processing, and ligation of the two ends of a broken DNA molecule. The individual roles of all key NHEJ enzymes are discussed, as well as the rare human disease patterns that can arise by impairment of these enzymes. In addition, a brief description is given of cellular processes, other than DSB repair, that also utilize the NHEJ machinery.
