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. 残り1件を表示 表示を減らす履歴 登録 2020年6月20日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2020年10月21日 Provider : repository / タイプ : Initial release改定 1.1 2020年11月4日 Group : Database references / カテゴリ : citation / citation_author改定 1.2 2021年1月20日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.year / _citation_author.identifier_ORCID 改定 1.3 2024年5月1日 Group : Data collection / Database references / カテゴリ : chem_comp_atom / chem_comp_bond / database_2Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession
