Here we provide a structure of the isolated yeast NPC in which the inner ring is resolved by cryo-EM at sub-nanometer resolution to show how flexible connectors tie together different structural and functional layers. These connectors may be targets for phosphorylation and regulated disassembly in cells with an open mitosis. Moreover, some nucleoporin pairs and transport factors have similar interaction motifs, which suggests an evolutionary and mechanistic link between assembly and transport. We provide evidence for three major NPC variants that may foreshadow functional specializations at the nuclear periphery. Cryo-electron tomography extended these studies, providing a model of the in situ NPC with a radially expanded inner ring. Our comprehensive model reveals features of the nuclear basket and central transporter, suggests a role for the lumenal Pom152 ring in restricting dilation, and highlights structural plasticity that may be required for transport. | ||||||||||||||||||||||||

Vitrification | Cryogen name: ETHANE-PROPANE Details: A custom-built vitrification device (Max Planck Institute for Biochemistry, Munich). |
Details | W303 yeast cells were harvested during log-phase growth and diluted to an 0.8 x 107 cells/mL in YPD media. Five uL of this diluted sample was applied to glow-discharged 200-mesh, Quantafoil R2/1 grids (Electron Microscopy Sciences), excess media was manually blotted from the grid back side (opposite to the carbon substrate where the cells were deposited) and the grid was plunge frozen in a liquid ethane-propane mixture (50/50 volume, Airgas) then cryogenic, FIB milling was performed in an Aquilos DualBeam (Thermo Fisher Scientific) |
