Muscle contraction relies on interaction between myosin-based thick filaments and actin-based thin filaments. Myosin binding protein C (MyBP-C) is a key regulator of actomyosin interactions. Recent studies established that the N'-terminal domains (NTDs) of MyBP-C can either activate or inhibit thin filaments, but the mechanism of their collective action is poorly understood. Cardiac MyBP-C (cMyBP-C) harbors an extra NTD, which is absent in skeletal isoforms of MyBP-C, and its role in regulation of cardiac contraction is unknown. Here we show that the first two domains of human cMyPB-C (i.e., C0 and C1) cooperate to activate the thin filament. We demonstrate that C1 interacts with tropomyosin via a positively charged loop and that this interaction, stabilized by the C0 domain, is required for thin filament activation by cMyBP-C. Our data reveal a mechanism by which cMyBP-C can modulate cardiac contraction and demonstrate a function of the C0 domain. 履歴 登録 2018年4月3日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2018年10月10日 Provider : repository / タイプ : Initial release改定 1.1 2018年12月19日 Group : Data collection / Database references / Structure summaryカテゴリ : citation / entityItem : _citation.journal_volume / _citation.page_first / _entity.formula_weight改定 1.2 2024年3月13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
