Structural basis for the simultaneous recognition of NEMO and acceptor ubiquitin by the HOIP NZF1 domain

open access: yesScientific Reports, 2022
Ubiquitination of NEMO by the linear ubiquitin chain assembly complex (LUBAC) is essential for activating the canonical NF-κB signaling pathway. While the NZF1 domain of the HOIP subunit of LUBAC recognizes the NEMO substrate, it is unclear how it ...

Protein unfolding and refolding as transitions through virtual states [PDF]

open access: yesEPL, 108 (2014) 28002, 2014
Single-molecule atomic force spectroscopy probes elastic properties of titin, ubiquitin and other relevant proteins. We explain bioprotein folding dynamics under both length- and force-clamp by modeling polyprotein modules as particles in a bistable potential, weakly connected by harmonic spring linkers.

Synergistic recruitment of UbcH7~Ub and phosphorylated Ubl domain triggers parkin activation [PDF]

open access: yes, 2018
The E3 ligase parkin ubiquitinates outer mitochondrial membrane proteins during oxidative stress and is linked to early-onset Parkinson’s disease. Parkin is autoinhibited but is activated by the kinase PINK1 that phosphorylates ubiquitin leading to ...

Ubiquitin in the immune system [PDF]

open access: yesEMBO reports, 2013
Ubiquitination is a post-translational modification process that has been implicated in the regulation of innate and adaptive immune responses. There is increasing evidence that both ubiquitination and its reversal, deubiquitination, play crucial roles not only during the development of the immune system but also in the orchestration of an immune ...

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

The Dual Roles of MAGE-C2 in p53 Ubiquitination and Cell Proliferation Through E3 Ligases MDM2 and TRIM28

open access: yesFrontiers in Cell and Developmental Biology, 2022
The tumor suppressor p53 is critical for the maintenance of genome stability and protection against tumor malignant transformation, and its homeostasis is usually regulated by ubiquitination.

Structural insight into SUMO chain recognition and manipulation by the ubiquitin ligase RNF4 [PDF]

open access: yes, 2014
The small ubiquitin-like modifier (SUMO) can form polymeric chains that are important signals in cellular processes such as meiosis, genome maintenance and stress response.

Lenalidomide induces ubiquitination and degradation of CK1α in del(5q) MDS

open access: yesNature, 2015
Lenalidomide is a highly effective treatment for myelodysplastic syndrome (MDS) with deletion of chromosome 5q (del(5q)). Here, we demonstrate that lenalidomide induces the ubiquitination of casein kinase 1A1 (CK1α) by the E3 ubiquitin ligase CUL4–RBX1 ...

Chemical Synthesis of Ubiquitin, Ubiquitin‐Based Probes, and Diubiquitin [PDF]

open access: yesAngewandte Chemie International Edition, 2010
Post-translational modification of proteins with ubiquitin (Ub) and Ub chains controls protein breakdown by the proteasome, cellular localization of proteins, transcriptional activity, and DNA repair.[1] Ubiquitin is a highly conserved 76 amino acid protein that can be linked to target proteins through an isopeptide bond between the C-terminal ...

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

open access: yesMolecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.
