The Nuclear Life of Nucleoporins [PDF]

Developmental Cell, 2007
Nucleoporins are the constituents of the nuclear pore complex, but they are also known to shuttle to the nuclear interior, the function of which is unclear. In a recent issue of Nature Cell Biology, Wang et al.'s mechanistic studies of leukemogenic fusion proteins that contain nucleoporins suggest that they have a direct role in transcription.

Role of Nucleoporins and Transport Receptors in Cell Differentiation

Frontiers in Physiology, 2020
Bidirectional molecular movements between the nucleus and cytoplasm take place through nuclear pore complexes (NPCs) embedded in the nuclear membrane.

Nucleoporins in cardiovascular disease

Journal of Molecular and Cellular Cardiology, 2020
Cardiovascular disease is a pressing health problem with significant global health, societal, and financial burdens. Understanding the molecular basis of polygenic cardiac pathology is thus essential to devising novel approaches for management and treatment.

Nucleoporin TPR is an integral component of the TREX-2 mRNA export pathway

Nature Communications, 2020
Nuclear pore complexes (NPCs) are important for cellular functions beyond nucleocytoplasmic trafficking, including genome organization and gene expression.

Crowding-induced phase separation of nuclear transport receptors in FG nucleoporin assemblies

bioRxiv, 2021
The rapid (< 1 ms) transport of biological material to and from the cell nucleus is regulated by the nuclear pore complex (NPC). At the core of the NPC is a permeability barrier consisting of intrinsically disordered Phe-Gly (FG) nucleoporins (FG Nups ...

Exportins can inhibit major mitotic assembly events in vitro: membrane fusion, nuclear pore formation, and spindle assembly

Nucleus, 2020
Xenopus egg extracts are a powerful in vitro tool for studying complex biological processes, including nuclear reconstitution, nuclear membrane and pore assembly, and spindle assembly.

Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly [PDF]

, 2011
During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules.

Higher nucleoporin-Importinβ affinity at the nuclear basket increases nucleocytoplasmic import. [PDF]

, 2013
Several in vitro studies have shown the presence of an affinity gradient in nuclear pore complex proteins for the import receptor Importinβ, at least partially contributing to nucleocytoplasmic transport, while others have historically argued against the

Translocation Biosensors – Cellular System Integrators to Dissect CRM1-Dependent Nuclear Export by Chemicogenomics

Sensors, 2009
Fluorescent protein biosensors are powerful cellular systems biology tools for dissecting the complexity of cellular processes with high spatial and temporal resolution. As regulated nucleo-cytoplasmic transport is crucial for the modulation of numerous (

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

Cell 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.
