Ubiquitin-Specific Proteases: Players in Cancer Cellular Processes
Pharmaceuticals, 2021 Ubiquitination represents a post-translational modification (PTM) essential for the maintenance of cellular homeostasis. Ubiquitination is involved in the regulation of protein function, localization and turnover through the attachment of a ubiquitin ...

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

Interplay between the Ubiquitin Proteasome System and Ubiquitin-Mediated Autophagy in Plants
Cells, 2020 All eukaryotes rely on the ubiquitin-proteasome system (UPS) and autophagy to control the abundance of key regulatory proteins and maintain a healthy intracellular environment. In the UPS, damaged or superfluous proteins are ubiquitinated and degraded in

Site-specific identification and quantitation of endogenous SUMO modifications under native conditions. [PDF]
, 2017 Small ubiquitin-like modifier (SUMO) modification regulates numerous cellular processes. Unlike ubiquitin, detection of endogenous SUMOylated proteins is limited by the lack of naturally occurring protease sites in the C-terminal tail of SUMO proteins ...

Detection of sequential polyubiquitylation on a millisecond timescale [PDF]
, 2009 The pathway by which ubiquitin chains are generated on substrate through a cascade of enzymes consisting of an E1, E2 and E3 remains unclear. Multiple distinct models involving chain assembly on E2 or substrate have been proposed.
