A Ubiquitinome Analysis to Study the Functional Roles of the Proteasome Associated Deubiquitinating Enzymes USP14 and UCH37 [PDF]
Journal of Proteomics, 2022 The removal of (poly)ubiquitin chains at the proteasome is a key step in the protein degradation pathway that determines which proteins are degraded and ultimately decides cell fate. Three different deubiquitinating enzymes (DUBs) are associated to the human proteasome, PSMD14 (RPN11), USP14 and UCH37 (UCHL5).

Proteomic approaches to study ubiquitinomics
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2023As originally described some 40 years ago, protein ubiquitination was thought to serve primarily as a static mark for protein degradation. In the ensuing years, it has become clear that 'ubiquitination' is a structurally diverse and dynamic post-translational modification and is intricately involved in a myriad of signaling pathways in all eukaryote ...

Ubiquitination of endogenous proteins is one of the key regulatory steps of protein degradation followed by regulation of proteasome activity. During the last years evidence has increased that proteasome activity is decreased during the aging process in various model systems and that these changes might be causally related to aging and aging associated

Molecular and Cellular Proteomics, 2019 Huntington's disease is caused by a polyglutamine repeat expansion in the huntingtin protein which affects the function and folding of the protein, and results in intracellular protein aggregates. Here, we examined whether this mutation leads to altered ubiquitination of huntingtin and other proteins in both soluble and insoluble fractions of brain ...

Phosphoproteomics and ubiquitinomics data-independent acquisition (DIA) mass spectrometry (MS) data is typically analyzed by using a data-dependent acquisition (DDA) spectral library. The performance of various library-free strategies for analyzing phosphoproteomics and ubiquitinomics DIA MS data has not been evaluated. In this study, we systematically

MycorrhizaInternational audienceThe regulation of cellular protein homeostasis involves the ubiquitin-proteasome system (UPS) by selectively targeting misfolded or end-of-life proteins. The involvement of the UPS in biotic stresses has been studied mainly in plant-

Decoding the ubiquitin landscape by cutting-edge ubiquitinomic approaches
Biochemical Society TransactionsFunctional consequences of protein ubiquitination have gone far beyond the degradation regulation as was initially imagined during its discovery 40 years back. The state-of-the-art has revealed the plethora of signaling pathways that are largely regulated by ubiquitination process in eukaryotes.

The patients with sigmoid colorectal cancer commonly show high mortality and poor prognosis. Increasing evidence has demonstrated that the ubiquitinated proteins and ubiquitination-mediated molecular pathways influence the growth and aggressiveness of colorectal cancer. It emphasizes the scientific merits of quantitative ubiquitinomics in human sigmoid

Parkinson's disease (PD), a neurodegenerative disorder, is significantly influenced by genetic predispositions, aging, and environmental factors. Central to PD pathology are mechanisms such as aberrant α-synuclein aggregation, mitochondrial dysfunction, oxidative stress, neuroinflammation, and ferroptosis, all of which are closely associated with ...
