Parkinson's disease is a progressive neuropathological disorder that belongs to the class of synucleinopathies, in which the protein alpha-synuclein is found at abnormally high concentrations in affected neurons. Its hallmark are intracellular inclusions called Lewy bodies and Lewy neurites. We here report the structure of cytotoxic alpha-synuclein fibrils (residues 1-121), determined by cryo-electron microscopy at a resolution of 3.4 Å. Two protofilaments form a polar fibril composed of staggered β-strands. The backbone of residues 38 to 95, including the fibril core and the non-amyloid component region, are well resolved in the EM map. Residues 50-57, containing three of the mutation sites associated with familial synucleinopathies, form the interface between the two protofilaments and contribute to fibril stability. A hydrophobic cleft at one end of the fibril may have implications for fibril elongation, and invites for the design of molecules for diagnosis and treatment of synucleinopathies. 履歴 登録 2018年7月26日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2018年8月8日 Provider : repository / タイプ : Initial release置き換え 2018年9月5日 ID : 6FLT 改定 1.1 2018年9月5日 Group : Advisory / Data collection / Database referencesカテゴリ : citation / citation_author / pdbx_database_PDB_obs_sprItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.journal_volume / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _citation_author.identifier_ORCID / _citation_author.name 改定 1.2 2019年12月18日 Group : Other / カテゴリ : atom_sitesItem : _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] / _atom_sites.fract_transf_matrix[3][3]改定 1.3 2023年2月22日 Group : Advisory / Database references / カテゴリ : database_2 / pdbx_database_PDB_obs_sprItem : _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _pdbx_database_PDB_obs_spr.replace_pdb_id改定 1.4 2024年7月10日 Group : Data collection / カテゴリ : chem_comp_atom / chem_comp_bond / em_admin / Item : _em_admin.last_update
