Loss of HSPA9 induces peroxisomal degradation by increasing pexophagy
Autophagy, 2020 Quality control of peroxisomes is essential for cellular homeostasis. However, the mechanism underlying pexophagy is largely unknown. In this study, we identified HSPA9 as a novel pexophagy regulator.

Molecular mechanism and physiological role of pexophagy
FEBS Letters, 2010 Pexophagy is a selective autophagy process wherein damaged and/or superfluous peroxisomes undergo vacuolar degradation. In methylotropic yeasts, where pexophagy has been studied most extensively, this process occurs by either micro- or macropexophagy ...

Pexophagy: Autophagic degradation of peroxisomes [PDF]
Biochimica Et Biophysica Acta - Molecular Cell Research, 2006 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

Cadmium induces reactive oxygen species‐dependent pexophagy in Arabidopsis leaves [PDF]
Plant, Cell and Environment, 2019 Cadmium treatment induces transient peroxisome proliferation in Arabidopsis leaves. To determine whether this process is regulated by pexophagy and to identify the mechanisms involved, we analysed time course-dependent changes in ATG8, an autophagy ...

Journal of Biological Chemistry, 2015 Pexophagy is a process that selectively degrades peroxisomes by autophagy. The Pichia pastoris pexophagy receptor Atg30 is recruited to peroxisomes under peroxisome proliferation conditions.

Deficiency of the exportomer components Pex1, Pex6, and Pex15 causes enhanced pexophagy inSaccharomyces cerevisiae [PDF]
Autophagy, 2014 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 ...
