RMND5 from Xenopus laevis is an E3 ubiquitin-ligase and functions in early embryonic forebrain development. [PDF]
In Saccharomyces cerevisiae the Gid-complex functions as an ubiquitin-ligase complex that regulates the metabolic switch between glycolysis and gluconeogenesis.

The NLRP3 inflammasome has a fundamental role in host defence against microbial pathogens and its deregulation may cause diverse inflammatory diseases. NLRP3 protein expression is a rate-limiting step for inflammasome activation, thus its expression must

The ubiquitination mediated by ubiquitin activating enzyme (E1), ubiquitin conjugating enzyme (E2), and ubiquitin ligase (E3) cascade is crucial to protein degradation, transcription regulation, and cell signaling in eukaryotic cells.

Ubiquitin Ligation without a Ligase [PDF]
Classically, ubiquitination requires three enzymes acting in sequence: E1, E2, and E3. E3 ubiquitin ligases typically provide substrate specificity. An article in Molecular Cell (Hoeller et al., 2007) now describes the E3-independent monoubiquitination of certain proteins. The mechanism has interesting parallels to SUMO ligation.

G Protein Mono-ubiquitination by the Rsp5 Ubiquitin Ligase [PDF]
Emerging evidence suggests that ubiquitination serves as a protein trafficking signal in addition to its well characterized role in promoting protein degradation. The yeast G protein α subunit Gpa1 represents a rare example of a protein that undergoes both mono- and poly-ubiquitination.

A Generic Platform for Cellular Screening Against Ubiquitin Ligases [PDF]
Ubiquitin signalling regulates most aspects of cellular life, thus deregulation of ubiquitylation has been linked with a number of diseases. E3 ubiquitin ligases provide substrate selectivity in ubiquitylation cascades and are therefore considered to be ...

Ubiquitin Ligases in Cholesterol Metabolism
To maintain cholesterol homeostasis, the processes of cholesterol metabolism are regulated at multiple levels including transcription, translation, and enzymatic activity. Recently, the regulation of protein stability of some key players in cholesterol metabolism has been characterized.

TRIM56 coiled-coil domain structure provides insights into its E3 ligase functions
Protein ubiquitination is a post-translation modification mediated by E3 ubiquitin ligases. The RING domain E3 ligases are the largest family of E3 ubiquitin ligases, they act as a scaffold, bringing the E2-ubiquitin complex and its substrate together to

The E3 ubiquitin ligase RNF185 facilitates the cGAS-mediated innate immune response
The cyclic GMP-AMP synthase (cGAS), upon cytosolic DNA stimulation, catalyzes the formation of the second messenger 2′3′-cGAMP, which then binds to stimulator of interferon genes (STING) and activates downstream signaling. It remains to be elucidated how

Ubiquitylation is a post-translational modification originally identified as the first step in protein degradation by the ubiquitin–proteasome system. Ubiquitylation is also known to regulate many cellular processes without degrading the ubiquitylated ...
