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.

An agent-based model for mRNA export through the nuclear pore complex. [PDF]

open access: yes, 2014
mRNA export from the nucleus is an essential step in the expression of every protein- coding gene in eukaryotes, but many aspects of this process remain poorly understood.

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 ...

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 ...

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

Evolution of the nucleus [PDF]

open access: yes, 2014
Under a Creative Commons license.The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells.

Temporal Changes in Nuclear Envelope Permeability during Semi-Closed Mitosis in Dictyostelium Amoebae

open access: yesCells, 2023
The Amoebozoan Dictyostelium discoideum exhibits a semi-closed mitosis in which the nuclear membranes remain intact but become permeabilized to allow tubulin and spindle assembly factors to access the nuclear interior.

Segregation of yeast nuclear pores [PDF]

open access: yesNature, 2010
During mitosis in Saccharomyces cerevisiae, senescence factors such as extrachromosomal ribosomal DNA circles (ERCs) are retained in the mother cell and excluded from the bud/daughter cell. Shcheprova et al. proposed a model suggesting segregation of ERCs through their association with nuclear pore complexes (NPCs) and retention of pre-existing NPCs in

In situ architecture of the algal nuclear pore complex

open access: yesNature Communications, 2018
Nuclear pore complexes (NPCs) span the nuclear envelope and mediate nucleocytoplasmic exchange. They are a hallmark of eukaryotes and deeply rooted in the evolutionary origin of cellular compartmentalization.

The molecular mechanism of nuclear transport revealed by atomic-scale measurements

open access: yeseLife, 2015
Nuclear pore complexes (NPCs) form a selective filter that allows the rapid passage of transport factors (TFs) and their cargoes across the nuclear envelope, while blocking the passage of other macromolecules.
