Generation and physiological roles of linear ubiquitin chains [PDF]

open access: yes, 2012
Ubiquitination now ranks with phosphorylation as one of the best-studied post-translational modifications of proteins with broad regulatory roles across all of biology.

The ubiquitin kinase PINK1 recruits autophagy receptors to induce mitophagy

open access: yesNature, 2015
Protein aggregates and damaged organelles are tagged with ubiquitin chains to trigger selective autophagy. To initiate mitophagy, the ubiquitin kinase PINK1 phosphorylates ubiquitin to activate the ubiquitin ligase parkin, which builds ubiquitin chains ...

Emerging functions of branched ubiquitin chains

open access: yesCell Discovery, 2021
Ubiquitylation is a critical post-translational modification that controls a wide variety of processes in eukaryotes. Ubiquitin chains of different topologies are specialized for different cellular functions and control the stability, activity ...

Ubiquitin, a central component of selective cytoplasmic proteolysis, is linked to proteins residing at the locus of non-selective proteolysis, the vacuole [PDF]

open access: yes, 1992
Ubiquitin, an evolutionary highly conserved protein, is known to be involved in selective proteolysis in the cytoplasm. Here we show that ubiquitin-protein conjugates are also found in the yeast vacuole.

In the family with ubiquitin [PDF]

open access: yesEMBO reports, 2011
The Cold Spring Harbor meeting on ‘The Ubiquitin family’, held in May 2011, brought together scientists from a wide range of fields, all under the common umbrella of ubiquitin and ubiquitin‐like protein structure, function and regulation.

CSF Ubiquitin Levels Are Higher in Alzheimer’s Disease than in Frontotemporal Dementia and Reflect the Molecular Subtype in Prion Disease

open access: yesBiomolecules, 2020
Disturbances in the ubiquitin-proteasome system seem to play a role in neurodegenerative dementias (NDs). Previous studies documented an increase of cerebrospinal fluid (CSF) free monoubiquitin in Alzheimer’s disease (AD) and Creutzfeldt− ...

Structural basis for the RING catalyzed synthesis of K63 linked ubiquitin chains [PDF]

open access: yes, 2015
This work was supported by grants from Cancer Research UK (C434/A13067), the Wellcome Trust (098391/Z/12/Z) and Biotechnology and Biological Sciences Research Council (BB/J016004/1).The RING E3 ligase catalysed formation of lysine 63 linked ubiquitin ...

Cellular quality control by the ubiquitin-proteasome system and autophagy

open access: yesScience, 2019
To achieve homeostasis, cells evolved dynamic and self-regulating quality control processes to adapt to new environmental conditions and to prevent prolonged damage.

The E3 Ubiquitin Ligase SIAH1 Targets MyD88 for Proteasomal Degradation During Dengue Virus Infection

open access: yesFrontiers in Microbiology, 2020
The dengue virus presents a serious threat to human health globally and can cause severe, even life-threatening, illness. Dengue virus (DENV) is endemic on all continents except Antarctica, and it is estimated that more than 100 million people are ...

Quantitative Cell-based Protein Degradation Assays to Identify and Classify Drugs That Target the Ubiquitin-Proteasome System [PDF]

open access: yes, 2011
We have generated a set of dual-reporter human cell lines and devised a chase protocol to quantify proteasomal degradation of a ubiquitin fusion degradation (UFD) substrate, a ubiquitin ligase CRL2^(VHL) substrate, and a ubiquitin-independent substrate ...
