One Ubiquitin, Two Ubiquitin, Three Ubiquitin, Four

Science's STKE, 2007
The 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.

Activation of Ubiquitin and Ubiquitin-Like Proteins

2010
Attachment 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

2016
Ubiquitination 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.

Ubiquitin and the synapse

Nature Reviews Neuroscience, 2002
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.

[Progress in ubiquitin, ubiquitin chain and protein ubiquitination].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2016
Protein 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 ...

Is This Protein Ubiquitinated?

2005
Covalent 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, 2005
The 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.

Ubiquitin in chains

Trends in Biochemical Sciences, 2000
The ubiquitin-proteasome system fulfills an essential function in eukaryotes by controlling the levels of crucial intracellular regulatory proteins. In this system, a specific type of polyubiquitin chain acts as the proximal signal for targeting substrates to 26S proteasomes for degradation.

The ubiquitin system

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 proteins as multifunctional signals

Nature Reviews Molecular Cell Biology, 2005
Protein 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.
