The apoptotic protease-activating factor 1 (Apaf-1) controls the onset of many known forms of intrinsic apoptosis in mammals. Apaf-1 exists in normal cells as an autoinhibited monomer. Upon binding to cytochrome c and dATP, Apaf-1 oligomerizes into a heptameric complex known as the apoptosome, which recruits and activates cell-killing caspases. Here we present an atomic structure of an intact mammalian apoptosome at 3.8 Å resolution, determined by single-particle, cryo-electron microscopy (cryo-EM). Structural analysis, together with structure-guided biochemical characterization, uncovered how cytochrome c releases the autoinhibition of Apaf-1 through specific interactions with the WD40 repeats. Structural comparison with autoinhibited Apaf-1 revealed how dATP binding triggers a set of conformational changes that results in the formation of the apoptosome. Together, these results constitute the molecular mechanism of cytochrome c- and dATP-mediated activation of Apaf-1. 履歴 登録 2015年10月15日 登録サイト : RCSB / 処理サイト : PDBJ改定 1.0 2015年11月18日 Provider : repository / タイプ : Initial release改定 1.1 2017年1月18日 Group : Database references改定 1.2 2019年10月16日 Group : Data collection / Database references / Otherカテゴリ : cell / database_2 ... cell / database_2 / em_image_scans / em_software Item : _cell.Z_PDB / _cell.length_a ... _cell.Z_PDB / _cell.length_a / _cell.length_b / _cell.length_c / _em_software.name 改定 1.3 2019年12月18日 Group : Data collection / Database references / Other / カテゴリ : atom_sites / em_software / struct_ref_seq_difItem : _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] ... _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] / _atom_sites.fract_transf_matrix[3][3] / _em_software.image_processing_id / _struct_ref_seq_dif.details 改定 1.4 2024年11月20日 Group : Data collection / Database references ...
