Peroxisome assembly: matrix and membrane protein biogenesis
The biogenesis of peroxisomal matrix and membrane proteins is substantially different from the biogenesis of proteins of other subcellular compartments, such as mitochondria and chloroplasts, that are of endosymbiotic origin. Proteins are targeted to the peroxisome matrix through interactions between specific targeting sequences and receptor proteins, followed by protein translocation across th...
متن کاملCritical Review Peroxisome Matrix and Membrane Protein Biogenesis
Peroxisomes play an important role in lipid metabolic pathways and are implicated in many human disorders. Their biogenesis has been studied over the last two decades using many uniand multi-cellular model systems and many aspects of the mechanisms and proteins involved in peroxisome biogenesis are conserved from yeast to humans. In this manuscript we review the recent progress made in our unde...
متن کاملThe peroxin pex3p initiates membrane assembly in peroxisome biogenesis.
Rat cDNA encoding a 372-amino-acid peroxin was isolated, primarily by functional complementation screening, using a peroxisome-deficient Chinese hamster ovary cell mutant, ZPG208, of complementation group 17. The deduced primary sequence showed approximately 25% amino acid identity with the yeast Pex3p, thereby we termed this cDNA rat PEX3 (RnPEX3). Human and Chinese hamster Pex3p showed 96 and...
متن کاملPeroxisome Membrane Biogenesis: The Stage Is Set
Pex3p and Pex19p are key players in the post-translational import of peroxisomal membrane proteins. New data suggest that these peroxins act in tandem, Pex19p as a cytosolic chaperone and import receptor for peroxisomal membrane proteins, and Pex3p as docking factor at the peroxisomal membrane.
متن کاملPeroxisome biogenesis and positioning.
Plant peroxisomes are extremely dynamic, moving and undergoing changes of shape in response to metabolic and environmental signals. Matrix proteins are imported via one of two import pathways, depending on the targeting signal within the protein. Each pathway has a specific receptor but utilizes common membrane-bound translocation machinery. Current models invoke receptor recycling, which may i...
