Ubiquitination is one of the most important posttranslational modifications in all eukaryote
organisms. Ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and …

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 …

In eukaryotes, the ubiquitin–proteasome system participates in the control of signal
transduction events by selectively eliminating regulatory proteins. E3 ubiquitin ligases …

Rice, a monocot model crop, contains at least 48 putative E2 ubiquitin (Ub)-conjugating
enzymes. Based on homology comparisons with 40 Arabidopsis E2 proteins and 35 human …

Abstract Approximately 5% of the Arabidopsis (Arabidopsis thaliana) proteome is predicted
to be involved in the ubiquitination/26S proteasome pathway. The majority of these …

Ubiquitin (Ub) is a small peptide that is covalently attached to proteins in a posttranslational
reaction. Ubiquitination is a precise regulatory system that is present in all eukaryotic …

Ubiquitination is an essential post-translational signal that allows cells to adapt and respond
to environmental stimuli. Substrate modifications range from a single ubiquitin molecule to …

The ubiquitination/proteasome system is involved in nearly all plant signaling processes.
Many signaling components are degraded by the 26S proteasome upon ubiquitination by …

The variance of the U-box domain in 64 Arabidopsis thaliana (thale cress) E3s (ubiquitin-
protein ligases) was used to examine the interactions between E3s and E2s (ubiquitin …

The Arabidopsis genome was searched to identify predicted proteins containing armadillo
(ARM) repeats, a motif known to mediate protein-protein interactions in a number of different …
