Efficiency, selectivity, and robustness of nucleocytoplasmic transport. [PDF]

open access: yesPLoS Computational Biology, 2007
All materials enter or exit the cell nucleus through nuclear pore complexes (NPCs), efficient transport devices that combine high selectivity and throughput. NPC-associated proteins containing phenylalanine-glycine repeats (FG nups) have large, flexible,

Diversification of importin-α isoforms in cellular trafficking and disease states. [PDF]

open access: yes, 2015
The human genome encodes seven isoforms of importin α which are grouped into three subfamilies known as α1, α2 and α3. All isoforms share a fundamentally conserved architecture that consists of an N-terminal, autoinhibitory, importin-β-binding (IBB ...

RanBP1 Couples Nuclear Export and Golgi Regulation through LKB1 to Promote Cortical Neuron Polarity

open access: yesCell Reports, 2018
Summary: Neuronal polarity in the developing cortex begins during the early stages of neural progenitor migration toward the cortical plate and culminates with the specification of the axon and dendrites.

Nucleocytoplasmic Transport: Navigating the Channel [PDF]

open access: yesTraffic, 2003
Nucleocytoplasmic transport is mediated by shuttling receptors that recognize specific signals on protein or RNA cargoes and translocate the cargoes through the nuclear pore complex. Transport receptors appear to move through the nuclear pore complex by facilitated diffusion, involving repeated cycles of binding to and dissociation from nucleoporins ...

Pathogenic determinants and mechanisms of ALS/FTD linked to hexanucleotide repeat expansions in the C9orf72 gene. [PDF]

open access: yes, 2017
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two apparently distinct neurodegenerative diseases, the former characterized by selective loss of motor neurons in the brain and spinal cord and the latter characterized by ...

Calcium regulation of nucleocytoplasmic transport [PDF]

open access: yesProtein & Cell, 2011
Bidirectional trafficking of macromolecules between the cytoplasm and the nucleus is mediated by the nuclear pore complexes (NPCs) embedded in the nuclear envelope (NE) of eukaryotic cell. The NPC functions as the sole pathway to allow for the passive diffusion of small molecules and the facilitated translocation of larger molecules.

Exportin Crm1 is important for Swi6 nuclear shuttling and MBF transcription activation in Saccharomyces cerevisiae

open access: yesBMC Molecular and Cell Biology, 2022
Background Swi6 acts as a transcription factor in budding yeast, functioning in two different heterodimeric complexes, SBF and MBF, that activate the expression of distinct but overlapping sets of genes.

C9orf72 Toxic Species Affect ArfGAP-1 Function

open access: yesCells, 2023
Compelling evidence indicates that defects in nucleocytoplasmic transport contribute to the pathogenesis of amyotrophic lateral sclerosis (ALS). In particular, hexanucleotide (G4C2) repeat expansions in C9orf72, the most common cause of genetic ALS, have

Mutational analysis of the carbohydrate binding activity of the tobacco lectin [PDF]

open access: yes, 2010
At present the three-dimensional structure of the tobacco lectin, further referred to as Nictaba, and its carbohydrate-binding site are unresolved. In this paper, we propose a three-dimensional model for the Nictaba domain based on the homology between ...

Altered nucleocytoplasmic proteome and transcriptome distributions in an in vitro model of amyotrophic lateral sclerosis. [PDF]

open access: yesPLoS ONE, 2017
Aberrant nucleocytoplasmic localization of proteins has been implicated in many neurodegenerative diseases. Evidence suggests that cytoplasmic mislocalization of nuclear proteins such as transactive response DNA-binding protein 43 (TDP-43) and fused in ...
