The ESCRT-III protein VPS4, but not CHMP4B or CHMP2B, is pathologically increased in familial and sporadic ALS neuronal nuclei

open access: yesActa Neuropathologica Communications, 2021
Nuclear pore complex injury has recently emerged as an early and significant contributor to familial and sporadic ALS disease pathogenesis. However, the molecular events leading to this pathological phenomenon characterized by the reduction of specific ...

Characterization of nuclear pore complex targeting domains in Pom152 in Saccharomyces cerevisiae

open access: yesBiology Open, 2021
Pom152 is a transmembrane protein within the nuclear pore complex (NPC) of fungi that is important for NPC assembly and structure. Pom152 is comprised of a short amino-terminal region that remains on the cytosolic side of the nuclear envelope (NE) and ...

An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae

open access: yeseLife, 2022
The nuclear pore complex (NPC) is the central portal for macromolecular exchange between the nucleus and cytoplasm. In all eukaryotes, NPCs assemble into an intact nuclear envelope (NE) during interphase, but the process of NPC biogenesis remains poorly ...

Types of nuclear localization signals and mechanisms of protein import into the nucleus

open access: yesCell Communication and Signaling, 2021
Nuclear localization signals (NLS) are generally short peptides that act as a signal fragment that mediates the transport of proteins from the cytoplasm into the nucleus.

Uip4p modulates nuclear pore complex function in Saccharomyces cerevisiae

open access: yesNucleus, 2022
A double membrane bilayer perforated by nuclear pore complexes (NPCs) governs the shape of the nucleus, the prominent distinguishing organelle of a eukaryotic cell.

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

open access: yes, 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.

Baculovirus Nuclear Import: Open, Nuclear Pore Complex (NPC) Sesame

open access: yesViruses, 2013
Baculoviruses are one of the largest viruses that replicate in the nucleus of their host cells. During infection, the rod-shape, 250-nm long nucleocapsid delivers its genome into the nucleus.

Energetics of Transport through the Nuclear Pore Complex. [PDF]

open access: yesPLoS ONE, 2016
Molecular transport across the nuclear envelope in eukaryotic cells is solely controlled by the nuclear pore complex (NPC). The NPC provides two types of nucleocytoplasmic transport: passive diffusion of small molecules and active chaperon-mediated ...

Nuclear Envelope: Nuclear Pore Complexity [PDF]

open access: yesCurrent Biology, 2005
A new study shows that the filamentous fungus, Aspergillus nidulans, which has a closed mitosis, does not maintain a continuous permeability barrier during mitosis. This work challenges current views of the differences between closed and open mitosis and has implications for understanding mitotic specific changes in the nuclear pore complex and Ran ...

The nuclear pore primes recombination-dependent DNA synthesis at arrested forks by promoting SUMO removal

open access: yesNature Communications, 2020
In yeast, collapsed forks shift to the nuclear periphery to associate with two distinct perinuclear anchorage sites such as the nuclear pore complex. Here, the authors reveal the mechanisms engaged at nuclear pore complex facilitating fork integrity and ...
