| 1 | 8 Å structure of the outer rings of the Xenopus laevis nuclear pore complex obtained by cryo-EM and AI显示文摘The nuclear pore complex(NPC),one of the largest protein complexes in eukaryotes,serves as a physical gate to regulate nucleocytoplasmic transport.Here,we determined the 8Åresolution cryo-electron microscopic(cryo-EM)structure of the outer rings containing nuclear ring(NR)and cytoplasmic ring(CR)from the Xenopus laevis NPC,with local resolutions reaching 4.9Å.With the aid of AlphaFold2,we managed to build a pseudoatomic model of the outer rings,including the Y complexes and flanking components.In this most comprehensive and accurate model of outer rings to date,the almost complete Y complex structure exhibits much tighter interaction in the hub region.In addition to two copies of Y complexes,each asymmetric subunit in CR contains five copies of Nup358,two copies of the Nup214 complex,two copies of Nup205 and one copy of newly identified Nup93,while that in NR contains one copy of Nup205,one copy of ELYS and one copy of Nup93.These in-depth structural features represent a great advance in understanding the assembly of NPCs. | Linhua Tai Yun Zhu He Ren Xiaojun Huang Chuanmao Zhang Fei Sun | 2022 | Protein & Cell2022，13，10： | 1 |
