Accumulating evidence has revealed that the ubiquitin proteasome system plays
fundamental roles in the regulation of diverse cellular activities in eukaryotes. The ubiquitin …

Due to their sessile nature, plants depend on flexible regulatory systems that allow them to
adequately regulate developmental and physiological processes in context with …

The ubiquitin-26S proteasome system is important in the quality control of intracellular
proteins. The ubiquitin-26S proteasome system includes the E1 (ubiquitin activating), E2 …

Selective ubiquitination of proteins is directed by diverse families of ubiquitin-protein ligases
(or E3s) in plants. One important type uses Cullin-3 as a scaffold to assemble multisubunit …

Plants are constantly exposed to a variety of abiotic stresses, such as drought, heat, cold,
flood, and salinity. To survive under such unfavorable conditions, plants have evolutionarily …

Ubiquitin-protein ligases (E3s) are responsible for target recognition and subsequent
modification of selected substrates within the ubiquitin proteasomal system (UPS) …

One goal of plant genetic engineering is the manipulation of protein levels within crop
plants. New insights into the ubiquitin-dependent proteolytic pathway provide potential novel …

Ubiquitin is well established as a major modifier of signalling in eukaryotes. However, the
extent to which plants rely on ubiquitin for regulating their lifecycle is only recently becoming …

Post-translational modification is central to protein stability and to the modulation of protein
activity. Various types of protein modification, such as phosphorylation, methylation …

Ubiquitin/26S proteasome-mediated proteolysis controls the half-life of numerous critical
regulatory proteins and is an intimate regulatory component for nearly all aspects of cellular …
