Role of Ubiquitin-Mediated Degradation System in Plant Biology
Ubiquitin-mediated proteasomal degradation is an important mechanism to control protein load in the cells. Ubiquitin binds to a protein on lysine residue and usually promotes its degradation through 26S proteasome system. Abnormal proteins and regulators of many processes, are targeted for degradation by the ubiquitin-proteasome system. It allows cells to maintain the response to cellular level...
متن کاملRegulation of ubiquitin-proteasome system mediated degradation by cytosolic stress.
ER-associated, ubiquitin-proteasome system (UPS)-mediated degradation of the wild-type (WT) gap junction protein connexin32 (Cx32) is inhibited by mild forms of cytosolic stress at a step before its dislocation into the cytosol. We show that the same conditions (a 30-min, 42 degrees C heat shock or oxidative stress induced by arsenite) also reduce the endoplasmic reticulum (ER)-associated turno...
متن کاملFocus on ubiquitin in plant biology.
Ubiquitin and ubiquitin-like modifiers are small proteins that are covalently joined via their C-terminal carboxyl group to substrate proteins, often on a Lys residue, thereby modifying the stability, localization, or function of the target. Although ubiquitin is present in all eukaryotes, plants have an inordinate fondness for ubiquitin, as judged by the plethora of ubiquitin-protein ligases e...
متن کاملUpdate on Ubiquitin-Mediated Control of Plant Hormone Signaling Ubiquitin-Mediated Control of Plant Hormone Signaling
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-studied area of transcriptional regulation for importance in cellular regulation. In this Update, we will highlight current research findings that illustrate the contributions of the UPS to phytohormone signaling....
متن کاملUbiquitin-Mediated Degradation of Aurora Kinases
The Aurora kinases are essential regulators of mitosis in eukaryotes. In somatic cell divisions of higher eukaryotes, the paralogs Aurora kinase A (AurA) and Aurora kinase B (AurB) play non-overlapping roles that depend on their distinct spatiotemporal activities. These mitotic roles of Aurora kinases depend on their interactions with different partners that direct them to different mitotic des...
