Mortalin/HSPA9 was identified as a pexophagy regulator and shown to partiallylocalize to peroxisomes, where it has been proposed to suppress the generationof pexophagy-promoting ROS [22].Reduction of this protein has been linked to neurodegenerative diseases such asParkinson’s and Alzheimer’s [29–31]. Here, HSPA9 is linked to neurodegenerative disease.
