Inhibitor of apoptosis proteins (IAPs) bind to pro-apoptotic proteases, keeping them inactive and preventing cell death. The atypical ubiquitin ligase BIRC6 is the only essential IAP, additionally functioning as a suppressor of autophagy. We performed a structure-function analysis of BIRC6 in complex with caspase-9, HTRA2, SMAC, and LC3B, which are critical apoptosis and autophagy proteins. Cryo-electron microscopy structures showed that BIRC6 forms a megadalton crescent shape that arcs around a spacious cavity containing receptor sites for client proteins. Multivalent binding of SMAC obstructs client binding, impeding ubiquitination of both autophagy and apoptotic substrates. On the basis of these data, we discuss how the BIRC6/SMAC complex can act as a stress-induced hub to regulate apoptosis and autophagy drivers. 履歴 登録 2022年8月25日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2023年2月15日 Provider : repository / タイプ : Initial release改定 1.1 2023年2月22日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.page_first / _citation.page_last ... _citation.page_first / _citation.page_last / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title 改定 1.2 2023年3月29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_author.identifier_ORCID 改定 1.3 2023年5月24日 Group : Structure summary / カテゴリ : struct / Item : _struct.title改定 1.4 2024年7月24日 Group : Data collection / Refinement descriptionカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / em_3d_fitting_list / em_admin Item : _em_3d_fitting_list.accession_code / _em_3d_fitting_list.initial_refinement_model_id ... _em_3d_fitting_list.accession_code / _em_3d_fitting_list.initial_refinement_model_id / _em_3d_fitting_list.source_name / _em_3d_fitting_list.type / _em_admin.last_update
