    ..The results merge into a picture in which removal of ubiquitin from the PTS1 receptor Pex5p is a specific event and might represent a vital step in receptor recycling...
  2. Grunau S, Lay D, Mindthoff S, Platta H, Girzalsky W, Just W, et al. The phosphoinositide 3-kinase Vps34p is required for pexophagy in Saccharomyces cerevisiae. Biochem J. 2011;434:161-70 pubmed publisher

    ..We conclude that Pex8p organizes the formation of the larger import complex from the trans side of the peroxisomal membrane and thus might enable functional communication between both sides of the membrane. ..

    ..By adding the heterologous binding site of Pex11p, peroxisomal targeting of the Pex13p fragment was restored. We conclude that Pex19p-binding sites are well-defined entities that represent an essential part of the mPTS. ..
  6. Halbach A, Lorenzen S, Landgraf C, Volkmer Engert R, Erdmann R, Rottensteiner H. Function of the PEX19-binding site of human adrenoleukodystrophy protein as targeting motif in man and yeast. PMP targeting is evolutionarily conserved. J Biol Chem. 2005;280:21176-82 pubmed
    ..Our data clearly revealed a role for PEX19-binding sites as PMP-targeting motifs across species, thereby demonstrating the evolutionary conservation of PMP signal sequences from yeast to man...

    ..However, loss of the ppg1 gene does not affect vegetative growth or fertility. Finally, we established the yeast assay as an easy and useful system for analyzing pheromone production in developmental mutants of S. macrospora. ..
  8. Erdmann R, Veenhuis M, Mertens D, Kunau W. Isolation of peroxisome-deficient mutants of Saccharomyces cerevisiae. Proc Natl Acad Sci U S A. 1989;86:5419-23 pubmed
    ..These pas mutants may provide useful tools for future studies on the molecular mechanisms involved in peroxisomal assembly. ..
  9. Halbach A, Landgraf C, Lorenzen S, Rosenkranz K, Volkmer Engert R, Erdmann R, et al. Targeting of the tail-anchored peroxisomal membrane proteins PEX26 and PEX15 occurs through C-terminal PEX19-binding sites. J Cell Sci. 2006;119:2508-17 pubmed
    ..We conclude that C-terminal PEX19-binding sites mark tail-anchored proteins for delivery to peroxisomes. ..

    ..We conclude that natural or artificial targeting of Pex3p to any endomembrane may initiate peroxisome formation and that also Pex3p-containing mitochondria can serve as source for the de novo synthesis of peroxisomes. ..

    ..Thus, isoprenylation of Pex19p contributes to substrate membrane protein recognition for the topogenesis of PMPs, and our results highlight the importance of lipid modifications in protein-protein interactions. ..
