A pex1 missense mutation improves peroxisome function in a subset of Arabidopsis pex6 mutants without restoring PEX5 recycling

Abstract excerpt

Significance ATPases have diverse cellular roles, including extracting proteins from membranes to maintain organellar function. The PEX1–PEX6 heterohexameric ATPases are thought to retrotranslocate PEX5 from the peroxisome membrane, and PEX1–PEX6 dysfunction impairs peroxisome biogenesis in humans and plants. We implemented a pex6 suppressor screen in Arabidopsis and recovered a compensatory pex1 allele that...
