The nuclear ubiquitin-proteasome system [PDF]

open access: yesJournal of Cell Science, 2006
In eukaryotes, thousands of genes have to be organized and expressed in the cell nucleus. Conformational and kinetic instability of nuclear structure and components appear to enable cells to use the encoded information selectively. The ubiquitin-proteasome system is active in distinct nuclear domains and plays a major role controlling the initial steps

The ubiquitin‐proteasome system in Alzheimer's disease [PDF]

open access: yesJournal of Cellular and Molecular Medicine, 2008
Introduction Biology of the UPS The involvement of the UPS in AD pathogenesis The UPS as a link between Aβ and tau interaction Conclusions AbstractAccumulation of proteins is a recurring event in many neurodegenerative diseases, including Alzheimer's disease (AD).Evidence has suggested that protein accumulation may result from a dysfunction in the ...

The proteasome cap RPT5/Rpt5p subunit prevents aggregation of unfolded ricin A chain [PDF]

open access: yes, 2013
The plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the endoplasmic reticulum (ER) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and ...

The Role of Ubiquitin-Proteasome System in the Pathogenesis of Severe Acute Respiratory Syndrome Coronavirus-2 Disease

open access: yesInternational Journal of Inflammation, 2023
Different protein degradation pathways exist in cells. However, the bulk of cellular proteins are degraded by the ubiquitin-proteasome system (UPS), which is one of these pathways.

Dual Function of USP14 Deubiquitinase in Cellular Proteasomal Activity and Autophagic Flux

open access: yesCell Reports, 2018
Summary: The ubiquitin-proteasome system and the autophagy-lysosome system are two major intracellular proteolytic pathways in eukaryotes. Although several biochemical mechanisms underlying the crosstalk between them have been suggested, little is known ...

Site-Specific Proteasome Inhibitors

open access: yesBiomolecules, 2021
Proteasome is a multi-subunit protein degradation machine, which plays a key role in the maintenance of protein homeostasis and, through degradation of regulatory proteins, in the regulation of numerous cell functions. Proteasome inhibitors are essential

Viral entry and the ubiquitin‐proteasome system [PDF]

open access: yesCellular Microbiology, 2020
Viruses confiscate cellular components of the ubiquitin-proteasome system (UPS) to facilitate many aspects of the infectious cycle. The 26S proteasome is an ATP-dependent, multisubunit proteolytic machine present in all eukaryotic cells. The proteasome executes the controlled degradation of functional proteins, as well as the hydrolysis of aberrantly ...

Chemical proteasome inhibition as a novel animal model of inner retinal degeneration in rats.

open access: yesPLoS ONE, 2019
Chemical proteasome inhibition has been a valuable animal model of neurodegeneration to uncover roles for the ubiquitin-proteasome system in the central nervous system.
