Kinesin-14 is a unique minus-end-directed microtubule-based motor. A swinging motion of a class-specific N-terminal neck helix has been proposed to produce minus-end directionality. However, it is unclear how swinging of the neck helix is driven by ATP hydrolysis utilizing the highly conserved catalytic core among all kinesins. Here, using a motility assay, we show that in addition to the neck helix, the conserved five residues at the C-terminal region in kinesin-14, namely the neck mimic, are necessary to give kinesin-1 an ability to reverse its directionality toward the minus end of microtubules. Our structural analyses further demonstrate that the C-terminal neck mimic, in cooperation with conformational changes in the catalytic core during ATP binding, forms a kinesin-14 bundle with the N-terminal neck helix to swing toward the minus end of microtubules. Thus, the neck mimic plays a crucial role in coupling the chemical ATPase reaction with the mechanical cycle to produce the minus-end-directed motility of kinesin-14. 履歴 登録 2016年1月19日 登録サイト : RCSB / 処理サイト : PDBJ改定 1.0 2016年8月10日 Provider : repository / タイプ : Initial release改定 1.1 2017年12月6日 Group : Data collection / Database references / カテゴリ : citation / em_image_scansItem : _citation.journal_id_ISSN / _citation.journal_volume ... _citation.journal_id_ISSN / _citation.journal_volume / _citation.page_first / _citation.page_last 改定 1.2 2018年7月25日 Group : Data collection / Database references / Source and taxonomyカテゴリ : citation / entity_src_genItem : _citation.title / _entity_src_gen.gene_src_common_name改定 1.3 2024年10月9日 Group : Data collection / Database references ...
