Electron tomography reveals posttranscriptional binding of pre-mRNPs to specific fibers in the nucleoplasm [PDF]
, 2000 International audienceUsing electron tomography, we have analyzed whether the Balbiani ring (BR) pre-mRNP particles in transit from the gene to the nuclear pore complex (NPC) are bound to any structure that could impair free diffusion through the ...

Structural and Biochemical Studies of the Human DEAD-box Helicase Dbp5 and Nucleoporin Nup214 Involved in mRNA Export [PDF]
, 2009 The hallmark of eukaryotic evolution was the development of the nucleus in cells. This compartmentalization requires the nucleocytoplasmic transport of thousands of molecules. The gate into and out of the nucleus is the nuclear pore complex (NPC). One of

Nuclear Pore Complexes: Guardians of the Nuclear Genome [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2010 Eukaryotic cell function depends on the physical separation of nucleoplasmic and cytoplasmic components by the nuclear envelope (NE). Molecular communication between the two compartments involves active, signal-mediated trafficking, a function that is exclusively performed by nuclear pore complexes (NPCs).

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Herpes simplex virus ICP27 protein directly interacts with the nuclear pore complex through NUP62, inhibiting host nucleocytoplasmic transport pathways [PDF]
, 2012 The herpes simplex virus ICP27 protein is important for the expression and nuclear export of viral mRNAs. Although several binding sites have been mapped along the ICP27 sequence for various RNA and protein partners including the transport receptor TAP ...

Regulation of diverse nuclear shapes: pathways working independently, together
Communicative & Integrative Biology, 2021 Membrane-bound organelles provide physical and functional compartmentalization of biological processes in eukaryotic cells. The characteristic shape and internal organization of these organelles is determined by a combination of multiple internal and ...

The Role of Nucleoporins in Cardiac Tissue Development and Disease
Frontiers in Bioscience-Landmark, 2023 Nuclear pore complexes (NPCs) are intricate intracellular structures composed of approximately 30 nuclear pore proteins (NUPs) that regulate the transport of materials between the nucleus and cytoplasm in eukaryotic cells.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
