Peroxisome degradation in mammals: mechanisms of action, recent advances, and perspectives
Peroxisomes are remarkably dynamic organelles that participate in a diverse array of cellular processes, including the metabolism of lipids and reactive oxygen species. In order to regulate peroxisome function in response to changing nutritional and environmental stimuli, new organelles need to be formed and superfluous and dysfunctional organelles have to be selectively removed. Disturbances i...
متن کاملPeroxisome-associated matrix protein degradation in Arabidopsis.
Peroxisomes are ubiquitous eukaryotic organelles housing diverse enzymatic reactions, including several that produce toxic reactive oxygen species. Although understanding of the mechanisms whereby enzymes enter peroxisomes with the help of peroxin (PEX) proteins is increasing, mechanisms by which damaged or obsolete peroxisomal proteins are degraded are not understood. We have exploited unique ...
متن کاملPeroxisome biogenesis and degradation in yeast: a structure/function analysis.
In yeast, peroxisomes are the site of specific catabolic pathways that characteristically include hydrogen peroxide producing oxidases and catalase. During the last 10 years, much progress has been made in unravelling the molecular mechanisms involved in the biogenesis of this organelle. At present, 23 different genes (PEX genes) have been identified that are involved in different aspects of pe...
متن کاملSenSing and Signaling for PeroxiSome autoPhagic degradation (PexoPhagy) in yeaStS
yeast cells, similarly to cells of other eukaryotic organisms, possess intracellular organelles, including that of peroxisomes also known as microbodies . Enzymes of oxidative metabolism, mainly hydrogen peroxide generating oxidases, catalase, some enzymes of glyoxylic cycle and enzymes involved in catabolism of unusual carbon sources (n-alkanes, methanol) are located in peroxisomes. Especially...
متن کاملGolgi membrane-associated degradation pathway in yeast and mammals.
Autophagy is a cellular process that degrades subcellular constituents, and is conserved from yeast to mammals. Although autophagy is believed to be essential for living cells, cells lacking Atg5 or Atg7 are healthy, suggesting that a non-canonical degradation pathway exists to compensate for the lack of autophagy. In this study, we show that the budding yeast Saccharomyces cerevisiae, which la...
