Pex3-anchored Atg36 tags peroxisomes for degradation in Saccharomyces cerevisiae
Peroxisomes undergo rapid, selective autophagic degradation (pexophagy) when the metabolic pathways they contain are no longer required for cellular metabolism. Pex3 is central to the formation of peroxisomes and their segregation because it recruits factors specific for these functions. Here, we describe a novel Saccharomyces cerevisiae protein that interacts with Pex3 at the peroxisomal membr...
متن کاملPpAtg30 tags peroxisomes for turnover by selective autophagy.
Autophagy, an intrinsically nonselective process, can also target selective cargo for degradation. The mechanism of selective peroxisome turnover by autophagy-related processes (pexophagy), termed micropexophagy and macropexophagy, is unknown. We show how a Pichia pastoris protein, PpAtg30, mediates peroxisome selection during pexophagy. It is necessary for pexophagy, but not for other selectiv...
متن کاملPexophagy: autophagic degradation of peroxisomes.
The abundance of peroxisomes within a cell can rapidly decrease by selective autophagic degradation (also designated pexophagy). Studies in yeast species have shown that at least two modes of peroxisome degradation are employed, namely macropexophagy and micropexophagy. During macropexophagy, peroxisomes are individually sequestered by membranes, thus forming a pexophagosome. This structure fus...
متن کاملDeficiency of the exportomer components Pex1, Pex6, and Pex15 causes enhanced pexophagy in Saccharomyces cerevisiae
Turnover of damaged, dysfunctional, or excess organelles is critical to cellular homeostasis. We screened mutants disturbed in peroxisomal protein import, and found that a deficiency in the exportomer subunits Pex1, Pex6, and Pex15 results in enhanced turnover of peroxisomal membrane structures compared with other mutants. Strikingly, almost all peroxisomal membranes were associated with phagop...
متن کاملContribution of the Endoplasmic Reticulum to Peroxisome Formation
How peroxisomes are formed in eukaryotic cells is unknown but important for insight into a variety of diseases. Both human and yeast cells lacking peroxisomes due to mutations in PEX3 or PEX19 genes regenerate the organelles upon reintroduction of the corresponding wild-type version. To evaluate how and from where new peroxisomes are formed, we followed the trafficking route of newly made YFP-t...
