Ubiquitin ligases (E3s) are pivotal specificity determinants in the ubiquitin system by selecting substrates and decorating them with distinct ubiquitin signals. However, structure determination of the underlying, specific E3-substrate complexes has proven challenging owing to their transient nature. In particular, it is incompletely understood how members of the catalytic cysteine-driven class of HECT-type ligases (HECTs) position substrate proteins for modification. Here, we report a cryogenic electron microscopy (cryo-EM) structure of the full-length human HECT HACE1, along with solution-based conformational analyses by small-angle X-ray scattering and hydrogen-deuterium exchange mass spectrometry. Structure-based functional analyses in vitro and in cells reveal that the activity of HACE1 is stringently regulated by dimerization-induced autoinhibition. The inhibition occurs at the first step of the catalytic cycle and is thus substrate-independent. We use mechanism-based chemical crosslinking to reconstitute a complex of activated, monomeric HACE1 with its major substrate, RAC1, determine its structure by cryo-EM and validate the binding mode by solution-based analyses. Our findings explain how HACE1 achieves selectivity in ubiquitinating the active, GTP-loaded state of RAC1 and establish a framework for interpreting mutational alterations of the HACE1-RAC1 interplay in disease. More broadly, this work illuminates central unexplored aspects in the architecture, conformational dynamics, regulation and specificity of full-length HECTs. 履歴 登録 2023年7月28日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2024年1月10日 Provider : repository / タイプ : Initial release改定 1.1 2024年2月21日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _citation_author.name 改定 1.2 2024年2月28日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first / _citation.page_last改定 1.3 2024年10月23日 Group : Data collection / Structure summaryカテゴリ : em_admin / pdbx_entry_details / pdbx_modification_featureItem : _em_admin.last_update / _pdbx_entry_details.has_protein_modification
