Proteasome activators.
Proteasomes degrade a multitude of protein substrates in the cytosol and nucleus, and thereby are essential for many aspects of cellular function. Because the proteolytic sites are sequestered in a closed barrel-shaped structure, activators are required to facilitate substrate access. Structural and biochemical studies of two activator families, 11S and Blm10, have provided insights to proteaso...
متن کاملActivators of yeast hexokinase.
The rate of the ATP:glucose transphosphorylase reaction catalyzed by yeast hexokinase, isozyme PII, is inhibited by lowering the pH of the reaction below 7.0, especially at suboptimal concentrations of ATP. This effect of acidity is largely overcome by activators such as orthophosphate, citrate, malate, 3-phosphoglycerate, and riboside triphosphates. Thus, in the acid range, ATP appears to serv...
متن کاملDietary activators of Sirt1.
Calorie restriction (CR) is a non-genetic manipulation that reliably results in extended lifespan of several species ranging from yeast to dogs. The lifespan extension effect of CR has been strongly associated with an increased level and activation of the silent information regulator 2 (Sir2) histone deacetylase and its mammalian ortholog Sirt1. This association led to the search for potential ...
متن کاملTranscriptional regulation: Kamikaze activators
Transcription factors are often targeted for rapid degradation by the ubiquitin-proteasome system. Recent evidence points to a correlation between the potency and instability of transcriptional activators, suggesting a possible direct role for ubiquitin-dependent proteolysis in transcriptional activation.
متن کاملTranscriptional Activators in Hepatocytes1
A longstanding quest of developmental biology has been to understand the molecular switches that determine which sets of genes are expressed in selected differentiated cell types. Since regulation of gene expression is predominantly at the level of mRNA synthesis (reviewed in Ref. 1), the problem initially becomes one of defining the protein factors that establish and maintain a gene in a trans...
