Authors: Amanda K Chaplin / Steven W Hardwick / Shikang Liang / Antonia Kefala Stavridi / Ales Hnizda / Lee R Cooper / Taiana Maia De Oliveira / Dimitri Y Chirgadze / Tom L Blundell / ![]() Abstract: DNA double-strand breaks are the most dangerous type of DNA damage and, if not repaired correctly, can lead to cancer. In humans, Ku70/80 recognizes DNA broken ends and recruits the DNA-dependent ...DNA double-strand breaks are the most dangerous type of DNA damage and, if not repaired correctly, can lead to cancer. In humans, Ku70/80 recognizes DNA broken ends and recruits the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) to form DNA-dependent protein kinase holoenzyme (DNA-PK) in the process of non-homologous end joining (NHEJ). We present a 2.8-Å-resolution cryo-EM structure of DNA-PKcs, allowing precise amino acid sequence registration in regions uninterpreted in previous 4.3-Å X-ray maps. We also report a cryo-EM structure of DNA-PK at 3.5-Å resolution and reveal a dimer mediated by the Ku80 C terminus. Central to dimer formation is a domain swap of the conserved C-terminal helix of Ku80. Our results suggest a new mechanism for NHEJ utilizing a DNA-PK dimer to bring broken DNA ends together. Furthermore, drug inhibition of NHEJ in combination with chemo- and radiotherapy has proved successful, making these models central to structure-based drug targeting efforts. #1: ![]() Title: Dimers of DNA-PK create a stage for DNA-double strand break repair Authors: Chaplin AK / Hardwick SW / Liang S / Stavridi AK / Hnizda A / Cooper LR / De Oliveira TM / Chirgadze DY / Blundell TL | |||||||||
