In Vitro Ubiquitination: Self-Ubiquitination, Chain Formation, and Substrate Ubiquitination Assays
2016Ubiquitination of proteins in vitro has evolved as an indispensable tool for the functional analysis of this posttranslational modification. In vitro ubiquitination is particularly helpful to study conjugation mechanisms. The efficiency of the ubiquitination reaction depends in part on the quality of the enzymes utilized.

Post-translational modification by the attachment of ubiquitin seems to have a crucial role in regulating synaptic structure and function. By controlling the stability, activity and localization of target proteins, this versatile regulatory system can shape the pattern, activity and plasticity of synaptic connections.

Annual Review of Biochemistry, 1998
The selective degradation of many short-lived proteins in eukaryotic cells is carried out by the ubiquitin system. In this pathway, proteins are targeted for degradation by covalent ligation to ubiquitin, a highly conserved small protein. Ubiquitin-mediated degradation of regulatory proteins plays important roles in the control of numerous processes ...

[Progress in ubiquitin, ubiquitin chain and protein ubiquitination].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2016Protein ubiquitination is one of the most important and widely exist protein post-translational modifications in eukaryotic cells, which takes the ubiquitin and ubiquitin chains as signal molecules to covalently modify other protein substrates. It plays an important roles in the control of almost all of the life processes, including gene transcription ...

The posttranslational modification with ubiquitin, a process referred to as ubiquitylation, controls almost every process in cells. Ubiquitin can be attached to substrate proteins as a single moiety or in the form of polymeric chains in which successive ubiquitin molecules are connected through specific isopeptide bonds.

Is This Protein Ubiquitinated?
2005Covalent modification of proteins with ubiquitin plays an important role in a wide array of cellular processes (Hershko and Ciechanover, 1998; Pickart, 2004). For this reason an increasing number of investigators in diverse research fields are confronted with the question whether their favorite proteins are ubiquitinated.

Proteomic insights into ubiquitin and ubiquitin-like proteins
Current Opinion in Chemical Biology, 2005The dynamic and specific modification of cellular proteins by members of the ubiquitin protein family is a vital regulatory mechanism that lies at the heart of almost all biological processes. Because of both their pervasive and complex nature, these regulatory pathways have been the target of many recent proteomic studies.

Eukaryotes contain a highly conserved multi-enzyme system that covalently links ubiquitin to a variety of intracellular proteins that bear degradation signals recognized by this system. The resulting ubiquitin-protein conjugates are degraded by the 26S proteasome, a large ATP-dependent protease.

The Ubiquitin Code in the Ubiquitin-Proteasome System and Autophagy
Trends in Biochemical Sciences, 2017The conjugation of the 76 amino acid protein ubiquitin to other proteins can alter the metabolic stability or non-proteolytic functions of the substrate. Once attached to a substrate (monoubiquitination), ubiquitin can itself be ubiquitinated on any of its seven lysine (Lys) residues or its N-terminal methionine (Met1).

Ubiquitin and ubiquitin-like proteins as multifunctional signals
Nature Reviews Molecular Cell Biology, 2005Protein ubiquitylation is a recognized signal for protein degradation. However, it is increasingly realized that ubiquitin conjugation to proteins can be used for many other purposes. Furthermore, there are many ubiquitin-like proteins that control the activities of proteins.
