The PEROXIN11 protein family controls peroxisome proliferation in Arabidopsis.
PEROXIN11 (PEX11) is a peroxisomal membrane protein in fungi and mammals and was proposed to play a major role in peroxisome proliferation. To begin understanding how peroxisomes proliferate in plants and how changes in peroxisome abundance affect plant development, we characterized the extended Arabidopsis thaliana PEX11 protein family, consisting of the three phylogenetically distinct subfami...
متن کاملSalt Stress Causes Peroxisome Proliferation, but Inducing Peroxisome Proliferation Does Not Improve NaCl Tolerance in Arabidopsis thaliana
The PEX11 family of peroxisome membrane proteins have been shown to be involved in regulation of peroxisome size and number in plant, animals, and yeast cells. We and others have previously suggested that peroxisome proliferation as a result of abiotic stress may be important in plant stress responses, and recently it was reported that several rice PEX11 genes were up regulated in response to a...
متن کاملArabidopsis peroxisome proteomics
The analytical depth of investigation of the peroxisomal proteome of the model plant Arabidopsis thaliana has not yet reached that of other major cellular organelles such as chloroplasts or mitochondria. This is primarily due to the difficulties associated with isolating and obtaining purified samples of peroxisomes from Arabidopsis. So far only a handful of research groups have been successful...
متن کاملPeroxisome proliferation and hepatocarcinogenesis.
Peroxisome proliferators constitute a novel class of non-mutagenic hepatocarcinogens, all of which induce a similar pleiotropic response consisting of hepatomegaly, proliferation of peroxisomes in the liver parenchyma] cells and the induction of several hepatic enzymes, particularly those of the peroxisomal fatty acid /3oxidation system (1—3). Presently several structurally dissimilar hypolipid...
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 ...
