Myosin X has features not found in other myosins. Its structure must underlie its unique ability to generate filopodia, which are essential for neuritogenesis, wound healing, cancer metastasis and some pathogenic infections. By determining high-resolution structures of key components of this motor, and characterizing the in vitro behaviour of the native dimer, we identify the features that explain the myosin X dimer behaviour. Single-molecule studies demonstrate that a native myosin X dimer moves on actin bundles with higher velocities and takes larger steps than on single actin filaments. The largest steps on actin bundles are larger than previously reported for artificially dimerized myosin X constructs or any other myosin. Our model and kinetic data explain why these large steps and high velocities can only occur on bundled filaments. Thus, myosin X functions as an antiparallel dimer in cells with a unique geometry optimized for movement on actin bundles. 履歴 登録 2016年2月4日 登録サイト : RCSB / 処理サイト : PDBE改定 1.0 2016年9月7日 Provider : repository / タイプ : Initial release改定 1.1 2016年9月14日 Group : Database references改定 1.2 2017年8月30日 Group : Author supporting evidence / カテゴリ : pdbx_audit_support / Item : _pdbx_audit_support.funding_organization改定 1.3 2019年10月16日 Group : Data collection / カテゴリ : reflns_shell改定 1.4 2024年5月8日 Group : Data collection / Database references / Derived calculationsカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / pdbx_struct_conn_angle / struct_conn Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession ... _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _pdbx_struct_conn_angle.ptnr1_auth_asym_id / _pdbx_struct_conn_angle.ptnr1_auth_comp_id / _pdbx_struct_conn_angle.ptnr1_auth_seq_id / _pdbx_struct_conn_angle.ptnr1_label_asym_id / _pdbx_struct_conn_angle.ptnr1_label_atom_id / _pdbx_struct_conn_angle.ptnr1_label_comp_id / _pdbx_struct_conn_angle.ptnr1_label_seq_id / _pdbx_struct_conn_angle.ptnr2_auth_asym_id / _pdbx_struct_conn_angle.ptnr2_auth_comp_id / _pdbx_struct_conn_angle.ptnr2_auth_seq_id / _pdbx_struct_conn_angle.ptnr2_label_asym_id / _pdbx_struct_conn_angle.ptnr2_label_atom_id / _pdbx_struct_conn_angle.ptnr2_label_comp_id / _pdbx_struct_conn_angle.ptnr3_auth_asym_id / _pdbx_struct_conn_angle.ptnr3_auth_comp_id / _pdbx_struct_conn_angle.ptnr3_auth_seq_id / _pdbx_struct_conn_angle.ptnr3_label_asym_id / _pdbx_struct_conn_angle.ptnr3_label_atom_id / _pdbx_struct_conn_angle.ptnr3_label_comp_id / _pdbx_struct_conn_angle.ptnr3_label_seq_id / _pdbx_struct_conn_angle.value / _struct_conn.pdbx_dist_value / _struct_conn.ptnr1_auth_asym_id / _struct_conn.ptnr1_auth_comp_id / _struct_conn.ptnr1_auth_seq_id / _struct_conn.ptnr1_label_asym_id / _struct_conn.ptnr1_label_atom_id / _struct_conn.ptnr1_label_comp_id / _struct_conn.ptnr1_label_seq_id / _struct_conn.ptnr2_auth_asym_id / _struct_conn.ptnr2_auth_comp_id / _struct_conn.ptnr2_auth_seq_id / _struct_conn.ptnr2_label_asym_id / _struct_conn.ptnr2_label_atom_id / _struct_conn.ptnr2_label_comp_id
