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 …

Owing to a sessile lifestyle in nature, plants are routinely faced with diverse hostile
environments such as various abiotic and biotic stresses, which lead to accumulation of free …

Posttranslational modifications of proteins by small polypeptides including ubiquitination,
neddylation (related to ubiquitin (RUB) conjugation), and sumoylation are implicated in plant …

Conjugation of multiple ubiquitins serves as a committed step in the degradation of a variety
of intracellular eukaryotic proteins by the 26S proteasome. Conjugates are formed via a …

The regulation of protein expression and activity has been for long time considered only in
terms of transcription/translation efficiency. In the last years, the discovery of post …

Ubiquitin-ligases or E3s are components of the ubiquitin proteasome system (UPS) that
coordinate the transfer of ubiquitin to the target protein. A major class of ubiquitin-ligases …

Major components of the ubiquitin proteasome system are the enzymes that operate on the
transfer of ubiquitin to selected target substrate, known as ubiquitin ligases. The RING finger …

Ubiquitin-mediated control of protein stability is central to most aspects of plant hormone
signaling. Attachment of ubiquitin to target proteins occurs via an enzymatic cascade with …

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 …

Covalent attachment of ubiquitin to other cellular proteins has been implicated in a multitude
of diverse physiological processes in eukaryotes including selective protein degradation …
