T-cell receptor (TCR) signaling promotes the assembly of RanBP2/RanGAP1-SUMO1/Ubc9 nuclear pore subcomplex via PKC-θ-mediated phosphorylation of RanGAP1

open access: yeseLife, 2021
The nuclear pore complex (NPC) is the sole and selective gateway for nuclear transport, and its dysfunction has been associated with many diseases. The metazoan NPC subcomplex RanBP2, which consists of RanBP2 (Nup358), RanGAP1-SUMO1, and Ubc9, regulates ...

HEPATITIS C VIRUS AND HOST CELL NUCLEAR TRANSPORT MACHINERY: A CLANDESTINE AFFAIR

open access: yesFrontiers in Microbiology, 2015
There is growing evidence that factors encoded by cytoplasmic replicating viruses functionally interact with components of the nucleocytoplasmic transport apparatus.

Nuclear Localization Signals for Optimization of Genetically Encoded Tools in Neurons

open access: yesFrontiers in Cell and Developmental Biology, 2022
Nuclear transport in neurons differs from that in non-neuronal cells. Here we developed a non-opsin optogenetic tool (OT) for the nuclear export of a protein of interest induced by near-infrared (NIR) light.

Structural Basis of Targeting the Exportin CRM1 in Cancer

open access: yesCells, 2015
Recent studies have demonstrated the interference of nucleocytoplasmic trafficking with the establishment and maintenance of various cancers. Nucleocytoplasmic transport is highly regulated and coordinated, involving different nuclear transport factors ...

Molecular determinants of large cargo transport into the nucleus

open access: yeseLife, 2020
Nucleocytoplasmic transport is tightly regulated by the nuclear pore complex (NPC). Among the thousands of molecules that cross the NPC, even very large (>15 nm) cargoes such as pathogens, mRNAs and pre-ribosomes can pass the NPC intact.

Nuclear Transport of Yeast Proteasomes

open access: yesBiomolecules, 2014
Proteasomes are conserved protease complexes enriched in the nuclei of dividing yeast cells, a major site for protein degradation. If yeast cells do not proliferate and transit to quiescence, metabolic changes result in the dissociation of proteasomes ...

Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

open access: yeseLife, 2019
Ran binding protein 1 (RanBP1) is a cytoplasmic-enriched and nuclear-cytoplasmic shuttling protein, playing important roles in nuclear transport. Much of what we know about RanBP1 is learned from fungi. Intrigued by the long-standing paradox of harboring

Active Nuclear Import of Membrane Proteins Revisited

open access: yesCells, 2015
It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). For the Saccharomyces cerevisiae proteins Src1/Heh1 and Heh2, a transport mechanism was proposed where ...

Viral Appropriation: Laying Claim to Host Nuclear Transport Machinery

open access: yesCells, 2019
Protein nuclear transport is an integral process to many cellular pathways and often plays a critical role during viral infection. To overcome the barrier presented by the nuclear membrane and gain access to the nucleus, virally encoded proteins have ...
