Deletion of proteasomal subunit S5a/Rpn10/p54 causes lethality, multiple mitotic defects and overexpression of proteasomal genes in Drosophila melanogaster [PDF]

open access: yes, 2003
The regulatory complex of the 26S proteasome is responsible for the selective recognition and binding of multiubiquitinated proteins. It was earlier shown that the subunit S5a/Rpn10/p54 of the regulatory complex is the only cellular protein capable of ...

The Ubiquitin–Proteasome System in Immune Cells

open access: yesBiomolecules, 2021
The ubiquitin–proteasome system (UPS) is the major intracellular and non-lysosomal protein degradation system. Thanks to its unique capacity of eliminating old, damaged, misfolded, and/or regulatory proteins in a highly specific manner, the UPS is ...

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 ...

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.

An extract of Artemisia dracunculus L. inhibits ubiquitin-proteasome activity and preserves skeletal muscle mass in a murine model of diabetes. [PDF]

open access: yesPLoS ONE, 2013
Impaired insulin signaling is a key feature of type 2 diabetes and is associated with increased ubiquitin-proteasome-dependent protein degradation in skeletal muscle. An extract of Artemisia dracunculus L.

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.

Characterization of the ubiquitylating components of the human malaria parasite's protein degradation pathway. [PDF]

open access: yesPLoS ONE, 2012
Ubiquitin-dependent protein degradation within malarial parasites is a burgeoning field of interest due to several encouraging reports of proteasome inhibitors that were able to confer antimalarial activity. Despite the growing interest in the Plasmodium

Molecular genetics of auxin signaling [PDF]

open access: yes, 2002
The plant hormone auxin is a simple molecule similar to tryptophan, yet it elicits a diverse array of responses and is involved in the regulation of growth and development throughout the plant life cycle.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Homo-PROTACs: bivalent small-molecule dimerizers of the VHL E3 ubiquitin ligase to induce self-degradation

open access: yesNature Communications, 2017
Targeting the ubiquitin proteasome system to modulate protein homeostasis using small molecules has promising therapeutic potential. Here the authors describe Homo-PROTACS: small molecules that can induce the homo-dimerization of E3 ubiquitin ligases and
