چکیده

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 understanding of the mechanisms by which matrix and membrane proteins are sorted to and assembled into peroxisomes. 2009 IUBMB IUBMB Life, 61(7): 713–722, 2009

Isolation and Characterization of a New Peroxisome Deficient CHO Mutant Cell Belonging to Complementation Group 12

We searched for novel Chinese hamster ovary (CHO) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (PTS) of Pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (EGFP). From mutagenized TKaEG3(1–40) cells, the wild-type CHO-K1 stably expressing rat Pex2p and of rat Pex3p(1–40)-EGFP, numerous cell colonies resistant to...

Import of peroxisomal matrix and membrane proteins.

This review summarizes the progress made in our understanding of peroxisome biogenesis in the last few years, during which the functional roles of many of the 23 peroxins (proteins involved in peroxisomal protein import and peroxisome biogenesis) have become clearer. Previous reviews in the field have focussed on the metabolic functions of peroxisomes, aspects of import/biogenesis the role of p...

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...

The importomer--a peroxisomal membrane complex involved in protein translocation into the peroxisome matrix.

The import of proteins into the peroxisome matrix is an essential step in peroxisome biogenesis, which is critical for normal functioning of most eukaryotic cells. The translocation of proteins across the peroxisome membrane and the dynamic behavior of the import receptors during the import cycle is facilitated by several peroxisome-membrane-associated protein complexes, one of which is called ...

Reevaluation of the role of Pex1 and dynamin-related proteins in peroxisome membrane biogenesis

A recent model for peroxisome biogenesis postulates that peroxisomes form de novo continuously in wild-type cells by heterotypic fusion of endoplasmic reticulum-derived vesicles containing distinct sets of peroxisomal membrane proteins. This model proposes a role in vesicle fusion for the Pex1/Pex6 complex, which has an established role in matrix protein import. The growth and division model pr...
