引用ジャーナル : Cell Rep / 年 : 2020タイトル : MZT Proteins Form Multi-Faceted Structural Modules in the γ-Tubulin Ring Complex.著者 : Michal Wieczorek / Tzu-Lun Huang / Linas Urnavicius / Kuo-Chiang Hsia / Tarun M Kapoor / 要旨 : Microtubule organization depends on the γ-tubulin ring complex (γ-TuRC), a ∼2.3-MDa nucleation factor comprising an asymmetric assembly of γ-tubulin and GCP2-GCP6. However, it is currently ... Microtubule organization depends on the γ-tubulin ring complex (γ-TuRC), a ∼2.3-MDa nucleation factor comprising an asymmetric assembly of γ-tubulin and GCP2-GCP6. However, it is currently unclear how the γ-TuRC-associated microproteins MZT1 and MZT2 contribute to the structure and regulation of the holocomplex. Here, we report cryo-EM structures of MZT1 and MZT2 in the context of the native human γ-TuRC. MZT1 forms two subcomplexes with the N-terminal α-helical domains of GCP3 or GCP6 (GCP-NHDs) within the γ-TuRC "lumenal bridge." We determine the X-ray structure of recombinant MZT1/GCP6-NHD and find it is similar to that within the native γ-TuRC. We identify two additional MZT/GCP-NHD-like subcomplexes, one of which is located on the outer face of the γ-TuRC and comprises MZT2 and GCP2-NHD in complex with a centrosomin motif 1 (CM1)-containing peptide. Our data reveal how MZT1 and MZT2 establish multi-faceted, structurally mimetic "modules" that can expand structural and regulatory interfaces in the γ-TuRC. 履歴 登録 2020年5月17日 - ヘッダ(付随情報) 公開 2020年7月22日 - マップ公開 2020年7月22日 - 更新 2024年3月6日 - 現状 2024年3月6日 処理サイト : RCSB / 状態 : 公開
