Ubiquitin proteomics identifies RNA polymerase I as a target of the Smc5/6 complex
Summary: Ubiquitination controls numerous cellular processes, and its deregulation is associated with many pathologies. The Nse1 subunit in the Smc5/6 complex contains a RING domain with ubiquitin E3 ligase activity and essential functions in genome ...

The reversible and irreversible protein posttranslational modifications, such as acetylation, methylation, phosphorylation, ubiquitination, glycosylation, SUMOylation, and redox modifications, are essential regulators in organisms and cells. This work systematically summarizes the features, regulatory mechanisms, substrates, functions, and related ...

Ubiquitous Ubiquitin: The K63 Ubiquitinome [PDF]
Polyubiquitination, the sequential attachment of the small 8 kDa globular protein ubiquitin (Ub) to target proteins, represents a major posttranslational modification that ultimately determines the substrate’s cellular fate. Ub conjugation is an extremely versatile form of protein regulation,

Detection of the Ubiquitinome in Cells Undergoing Oncogene-Induced Senescence [PDF]
Senescent cells exhibit dramatic changes in protein post-translational modifications. Here, we describe a method, stable isotope labeling with amino acids in cell culture (SILAC) coupled to liquid chromatography tandem mass spectrometry (LC-MS/MS), to identify changes in the ubiquitinome in cells that have undergone oncogene-induced senescence.

Abstract Ubiquitination is an essential post‐translational modification that regulates protein stability or function. Its substrate specificity is dictated by various E3 ligases. The human C‐terminal to LisH (CTLH) complex is a newly discovered multi‐subunit really interesting new gene (RING) E3 ligase with only a few known ubiquitination targets. Here,

Site-Specific K63 Ubiquitinomics Provides Insights into Translation Regulation under Stress [PDF]
During oxidative stress, K63-linked polyubiquitin chains modify a variety of proteins including ribosomes. Knowledge of the precise sites of K63 ubiquitin is key to understand its function during the response to stress. To identify the sites of K63 ubiquitin, we developed a new mass spectrometry based method that quantified >1100 K63 ubiquitination ...

Ubiquitination has crucial roles in many cellular processes, and dysregulation of ubiquitin machinery enzymes can result in various forms of pathogenesis. Cells only have a limited set of ubiquitin-conjugating (E2) enzymes to support the ubiquitination of many cellular targets.
