چکیده

Background: Pex5p translocates the cargo proteins into peroxisomes. Results:Mammalian RING peroxins, the Pex10p Pex12p complex, catalyze Lys-linked, multiple monoubiquitination of Pex5p, assuring efficient export of Pex5p from peroxisomes. Conclusion: Distinct Lysand Cys-linked modes of Pex5p ubiquitination control Pex5p-mediated matrix protein import. Significance: This work provides the first evidence of a functional role of mammalian RING peroxins in Pex5p ubiquitination.

Genetic Interactions between PEROXIN12 and Other Peroxisome-Associated Ubiquitination Components1[OPEN]

Most eukaryotic cells require peroxisomes, organelles housing fatty acid b-oxidation and other critical metabolic reactions. Peroxisomal matrix proteins carry peroxisome-targeting signals that are recognized by one of two receptors, PEX5 or PEX7, in the cytosol. After delivering the matrix proteins to the organelle, these receptors are removed from the peroxisomal membrane or matrix. Receptor r...

Peroxisomal matrix protein receptor ubiquitination and recycling.

The peroxisomal targeting signal type1 (PTS1) receptor Pex5 is required for the peroxisomal targeting of most matrix proteins. Pex5 recognises target proteins in the cytosol and directs them to the peroxisomal membrane where cargo is released into the matrix, and the receptor shuttles back to the cytosol. Recently, it has become evident that the membrane-bound Pex5 can be modified by mono- and ...

Peroxisome 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...

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...
