Posttranslational modifications add complexity and diversity to cellular proteomes. One of
the most prevalent modifications across eukaryotes is ubiquitination, which is orchestrated …

Ubiquitin-mediated proteolysis is an integral part of diverse cellular functions, and of the
three enzymes involved in linking ubiquitin to protein targets, the E3 ubiquitin ligases are of …

Background Plants respond to abiotic stress on physiological, biochemical and molecular
levels. This includes a global change in their cellular proteome achieved by changes in the …

U-box proteins, as well as other proteins involved in regulated protein degradation, are
apparently over-represented in Arabidopsis compared with other model eukaryotes. The …

The past decade has witnessed an explosion in the identification of ubiquitin-ligase
complexes as the missing receptors for important small-molecule hormones regulating plant …

The ubiquitin-proteasome system (UPS) plays a role in nearly every aspect of plant biology.
The wealth of emerging data demonstrates that regulated protein degradation rivals the well …

The plant U‐box (PUB) protein functions as an E3 ligase to poly‐ubiquitinate a target protein
for its degradation or post‐translational modification. Here, we report functional roles for …

U-box proteins are widely distributed among eukaryotic organisms and show a higher
prevalence in plants than in other organisms. Plant U-box (PUB) proteins play crucial …

The ubiquitin (Ub) system of intracellular protein degradation regulates the abundance of
numerous proteins that control plant growth and development. Recent advances have …

Background In plants, the ubiquitin-proteasome system is emerging as a significant
regulatory system throughout the plant lifecycle. The ubiquitination of a target protein …
