The unifying catalytic mechanism of the RING-between-RING E3 ubiquitin ligase family

open access: yesNature Communications, 2023
RBR E3 ubiquitin ligases utilise a 2-step catalytic mechanism previously defined for only few of the RBR family members. Here, the authors examine the poorly studied RBRs HOIL-1 and RNF216 to define general principles of RBR catalysis and regulation and ...

Research progress of RNF180 in gastric cancer

open access: yes生物医学转化, 2022
RNF180 is a type of ring finger protein with ubiquitin ligase activity, which can affect various physiological processes such as cell proliferation, differentiation and apoptosis by participating in the ubiquitinproteasome system. Studies have shown that

SPOP targets the immune transcription factor IRF1 for proteasomal degradation

open access: yeseLife, 2023
Adaptation of the functional proteome is essential to counter pathogens during infection, yet precisely timed degradation of these response proteins after pathogen clearance is likewise key to preventing autoimmunity. Interferon regulatory factor 1 (IRF1)

The Ubiquitin Ligase SIAH2 Negatively Regulates Glucocorticoid Receptor Activity and Abundance

open access: yesBiomedicines, 2020
Glucocorticoids are clinically essential drugs used routinely to control inflammation. However, a host of metabolic side effects manifests upon usage beyond a few days.

Interplay between septins and ubiquitin-mediated xenophagy during Shigella entrapment

open access: yesAutophagy Reports, 2023
Septins are cytoskeletal proteins implicated in numerous cellular processes including cytokinesis and morphogenesis. In the case of infection by Shigella flexneri, septins assemble into cage-like structures that entrap cytosolic bacteria targeted by ...

A Sensitive Yellow Fever Virus Entry Reporter Identifies Valosin-Containing Protein (VCP/p97) as an Essential Host Factor for Flavivirus Uncoating

open access: yesProceedings, 2020
Flaviviruses are enveloped, arthropod-borne, positive-strand RNA viruses that cause significant human disease. While the basic mechanisms of flavivirus entry and fusion are understood, little is known about the postfusion events that precede RNA ...

Deubiquitinating enzymes at the crossroads of lipid metabolism and cancer

open access: yesJournal of Biological Research - Thessaloniki, 2021
Deregulated lipid metabolism has been recognized as a critical alteration that supports the development and growth of various types of tumors. Changes in lipid metabolism enable reprogramming of energetics and availability of synthetic intermediates and ...

Assembly and disassembly of branched ubiquitin chains

open access: yesFrontiers in Molecular Biosciences, 2023
Protein ubiquitylation is an essential post-translational modification that regulates nearly all aspects of eukaryotic cell biology. A diverse collection of ubiquitylation signals, including an extensive repertoire of polymeric ubiquitin chains, leads to

Sugar-Recognizing Ubiquitin Ligases: Action Mechanisms and Physiology

open access: yesFrontiers in Physiology, 2019
F-box proteins, the substrate recognition subunits of SKP1–CUL1–F-box protein (SCF) E3 ubiquitin ligase complexes, play crucial roles in various cellular events mediated by ubiquitination.
