Activation of Ubiquitin and Ubiquitin-Like Proteins
2010Attachment of ubiquitin and ubiquitin-like proteins to cellular targets represents a fundamental regulatory strategy within eukaryotes and exhibits remarkably pleiotropic effects on cell function. These posttranslational modifications share a common mechanism comprised of three steps: an activating enzyme to couple ATP hydrolysis to formation of a high-

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.

One Ubiquitin, Two Ubiquitin, Three Ubiquitin, Four
Science's STKE, 2007The role of protein ubiquitination is well known in promoting regulated protein degradation. Mukhopadhyay and Riezman review what is known about the contribution of protein ubiquitination in other cellular pathways, including intracellular signaling, endocytosis, and protein sorting. D. Mukhopadhyay, H.

Modification of Proteins by Ubiquitin and Ubiquitin-Like Proteins [PDF]
Annual Review of Cell and Developmental Biology, 2006 Following the discovery of protein modification by the small, highly conserved ubiquitin polypeptide, a number of distinct ubiquitin-like proteins (Ubls) have been found to function as protein modifiers as well. These Ubls, which include SUMO, ISG15, Nedd8, and Atg8, function as critical regulators of many cellular processes, including 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.

Trends in Biochemical Sciences, 1997
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.

Ubiquitin and Ubiquitin-like Modifiers in Plants
Journal of Plant Biology, 2011Posttranslational modifications of proteins by small polypeptides including ubiquitination, neddylation (related to ubiquitin (RUB) conjugation), and sumoylation are implicated in plant growth and development, and they regulate protein degradation, location, and interaction with other proteins.

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.

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).
