USP30: protector of peroxisomes and mitochondria

Abstract

In our recent publication, we describe a mechanism by which peroxisomes are protected from degradation by autophagy under basal conditions. Taking a page from mitophagy, peroxisomes also recruit the mitochondria deubiquitinating enzyme USP30 to counter the action of PEX2, the peroxisomal E3 ubiquitin ligase to regulate pexophagy.
