The measurement of ubiquitin and ubiquitinated proteins
Electrophoresis, 1999Ubiquitination of key cellular proteins involved in signal transduction, gene transcription and cell-cycle regulation usually condemns those proteins to proteasomal or lysosomal degradation. Additionally, cycles of reversible ubiquitination regulate the function of certain proteins in a manner analogous to phosphorylation.

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.

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-

Analytical Biochemistry, 2017
Ubiquitin, a 76 amino acid protein, is a key component that contributes to cellular protein homeostasis. The specificity of this modification is due to a series of enzymes: ligases, attaching the ubiquitin to a lysine, and deubiquitinases, which remove it. More than a hundred of such proteins are implicated in the regulation of protein turnover.

[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 ...

When ubiquitin meets ubiquitin receptors: a signalling connection
Nature Reviews Molecular Cell Biology, 2003Ubiquitylation is emerging as a versatile device for controlling cellular functions. Here, we propose that monoubiquitylation is rapidly induced by signalling events and allows the establishment of protein-protein interactions between monoubiquitylated proteins and partners that contain distinct ubiquitin-binding domains.

Monitoring MHC Ubiquitination by MARCH Ubiquitin Ligases
2019Ubiquitination is a reversible process that controls the intracellular transport of many transmembrane molecules. Ubiquitination of MHC I, MHC II, and CD1a by different members of the MARCH family of E3 ubiquitin ligases is a key event in the regulation of the potent immunostimulatory properties of activated dendritic cells. We describe here methods to
