Sorting with Disorder at Nuclear Pores [PDF]

open access: yesBiophysical Journal, 2012
Macromolecular traffic between the nucleus and cytoplasm of cells is mediated by karyopherins and is gated at nuclear pores (NPCs) by intrinsically-disordered proteins featuring phenylalanine-glycine repeats: the FG nucleoporins. Despite their dynamic nature, these FG nups adopt distinct categories of disordered structure with unique functions.

Modeling of the mechano-chemical behavior of the nuclear pore complex: current research and perspectives [PDF]

open access: yes, 2016
Recent evidence suggests that mechanical deformation of the cell nucleus regulates the nuclear import of the transcriptional activators of genes involved in primary physiological cell responses such as stem cell differentiation. In addition, this nuclear

HIV-1 nuclear import in macrophages is regulated by CPSF6-capsid interactions at the nuclear pore complex

open access: yeseLife, 2019
Nuclear entry of HIV-1 replication complexes through intact nuclear pore complexes is critical for successful infection. The host protein cleavage-and-polyadenylation-specificity-factor-6 (CPSF6) has been implicated in different stages of early HIV-1 ...

Clathrate formation and dissociation in vapor/water/ice/hydrate systems in SBA-15, sol-gel and CPG porous media, as probed by NMR relaxation, novel protocol NMR cryoporometry, neutron scattering and ab initio quantum-mechanical molecular dynamics simulation [PDF]

open access: yes, 2007
The Gibbs-Thomson effect modifies the pressure and temperature at which clathrates occur, hence altering the depth at which they occur in the seabed. Nuclear magnetic resonance (NMR) measurements as a function of temperature are being conducted for water/

ON THE ATTACHMENT OF THE NUCLEAR PORE COMPLEX [PDF]

open access: yesThe Journal of Cell Biology, 1974
Electron microscope examination of isolated rat liver nuclei after treatment with the detergent Triton X-100 revealed the complete removal of both the inner and outer membranes of the nuclear envelope. The envelope-denuded nuclei did not show any change in either shape or internal ultrastructure.

TFEB/Mitf links impaired nuclear import to autophagolysosomal dysfunction in C9-ALS

open access: yeseLife, 2020
Disrupted nucleocytoplasmic transport (NCT) has been implicated in neurodegenerative disease pathogenesis; however, the mechanisms by which disrupted NCT causes neurodegeneration remain unclear.

Structure-function mapping of a heptameric module in the nuclear pore complex. [PDF]

open access: yes, 2012
The nuclear pore complex (NPC) is a multiprotein assembly that serves as the sole mediator of nucleocytoplasmic exchange in eukaryotic cells. In this paper, we use an integrative approach to determine the structure of an essential component of the yeast ...

The liquid state of FG-nucleoporins mimics permeability barrier properties of nuclear pore complexes

open access: yesJournal of Cell Biology, 2019
Nuclear pore complexes form a permeability barrier in vivo that regulates nucleocytoplasmic transport. Here, the authors present a microfluidic device that couples rapid liquid–liquid phase separation of nucleoporins with direct optical interrogation ...

Redox-Sensitive Cysteines Confer Proximal Control of the Molecular Crowding Barrier in the Nuclear Pore

open access: yesCell Reports, 2020
Summary: The nuclear pore complex forms a highly crowded selective barrier with intrinsically disordered regions at the nuclear membrane to coordinate nucleocytoplasmic molecular communications.

The nuclear pore primes recombination-dependent DNA synthesis at arrested forks by promoting SUMO removal

open access: yesNature Communications, 2020
In yeast, collapsed forks shift to the nuclear periphery to associate with two distinct perinuclear anchorage sites such as the nuclear pore complex. Here, the authors reveal the mechanisms engaged at nuclear pore complex facilitating fork integrity and ...
