Redox regulation of proteasome function
Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) were initially regarded mainly as metabolic by-products with damaging properties. Over the last decade, our understanding of their role in metabolism was drastically changed and they were recognized as essential mediators in cellular signaling cascades, as well as modulators of biochemical pathways. Proteostasis is highly affecte...
متن کاملRedox regulation of the proteasome via S-glutathionylation☆
The proteasome is a multimeric and multicatalytic intracellular protease responsible for the degradation of proteins involved in cell cycle control, various signaling processes, antigen presentation, and control of protein synthesis. The central catalytic complex of the proteasome is called the 20S core particle. The majority of these are flanked on one or both sides by regulatory units. Most c...
متن کاملDifferential regulation of proteasome function in isoproterenol-induced cardiac hypertrophy.
RATIONALE Proteasomal degradation is altered in many disease phenotypes including cardiac hypertrophy, a prevalent condition leading to heart failure. Our recent investigations identified heterogeneous subpopulations of proteasome complexes in the heart and implicated multiple mechanisms for their regulation. OBJECTIVE The study aimed at identification of molecular mechanisms changing proteas...
متن کاملThe proteasome and the degradation of oxidized proteins: Part III—Redox regulation of the proteasomal system
Here, we review shortly the current knowledge on the regulation of the proteasomal system during and after oxidative stress. After addressing the components of the proteasomal system and the degradation of oxidatively damaged proteins in part I and II of this series, we address here which changes in activity undergo the proteasome and the ubiquitin-proteasomal system itself under oxidative cond...
متن کاملRedox signaling in central neural regulation of cardiovascular function.
One of the most prominent concepts to emerge in cardiovascular research over the past decade, especially in areas focused on angiotensin II (AngII), is that reactive oxygen species (ROS) are critical signaling molecules in a wide range of cellular processes. Many of the physiological effects of AngII are mediated by ROS, and alterations in AngII-mediated redox mechanisms are implicated in cardi...
