Lipid Droplets Are a Physiological Nucleoporin Reservoir [PDF]
Cells, 2021 Lipid Droplets (LD) are dynamic organelles that originate in the Endoplasmic Reticulum and mostly bud off toward the cytoplasm, where they store neutral lipids for energy and protection purposes.

Dynamic rearrangement of nucleoporins during fungal "open" mitosis [PDF]
Molecular Biology of the Cell, 2008 Mitosis in animals starts with the disassembly of the nuclear pore complexes and the breakdown of the nuclear envelope. In contrast to many fungi, the corn smut fungus Ustilago maydis also removes the nuclear envelope.

The new nucleoporin: Regulator of transcriptional repression and beyond [PDF]
Nucleus, 2012 Transcriptional regulation is a complex process that requires the integrated action of many multi-protein complexes. The way in which a living cell coordinates the action of these complexes in time and space is still poorly understood.

Multifunctionality of F-rich nucleoporins [PDF]
Biochemical Society Transactions, 2020 Nucleoporins (Nups) represent a range of proteins most known for composing the macromolecular assembly of the nuclear pore complex (NPC). Among them, the family of intrinsically disordered proteins (IDPs) phenylalanine-glycine (FG) rich Nups, form the permeability barrier and coordinate the high-speed nucleocytoplasmic transport in a selective way ...

Autoproteolysis in nucleoporin biogenesis [PDF]
Proceedings of the National Academy of Sciences, 1999 We have molecularly characterized a proteolytic cleavage in conserved nuclear pore complex proteins. This cleavage, previously demonstrated to be essential for the biogenesis of two nuclear pore complex proteins in mammals (Nup98 and Nup96) and yeast (Nup145-N and Nup145-C), occurs between Phe and Ser residues within a highly conserved ...

Nucleoporin Nup358 Downregulation Tunes the Neuronal Excitability in Mouse Cortical Neurons
Life, 2023 Nucleoporins (NUPs) are proteins that comprise the nuclear pore complexes (NPCs). The NPC spans the nuclear envelope of a cell and provides a channel through which RNA and proteins move between the nucleus and the cytoplasm and vice versa.

Nucleoporin TPR is an integral component of the TREX-2 mRNA export pathway
Nature Communications, 2020 mRNAs export from the nucleus is thought to be regulated in part by three nucleoporins that comprise the nuclear basket, but whether and how distinct basket nucleoporins interact with the RNA export machinery is unclear. Here, the authors use rapid auxin-

Protein Subdomain Enrichment of NUP155 Variants Identify a Novel Predicted Pathogenic Hotspot
Frontiers in Cardiovascular Medicine, 2020 Functional variants in nuclear envelope genes are implicated as underlying causes of cardiopathology. To examine the potential association of single nucleotide variants of nucleoporin genes with cardiac disease, we employed a prognostic scoring approach ...

Nucleoporin Nup62 maintains centrosome homeostasis [PDF]
Cell Cycle, 2013 Centrosomes are comprised of 2 orthogonally arranged centrioles surrounded by the pericentriolar material (PCM), which serves as the main microtubule organizing center of the animal cell. More importantly, centrosomes also control spindle polarity and orientation during mitosis.

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
