Autophagy-related protein 32

Gene

ATG32

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Mitophagy-specific receptor that recruits the autophagic machinery to mitochondria and regulates selective degradation of mitochondria. Mitophagy contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production. Recruits ATG11 to the surface of mitochondria. Promotes also autophagy-dependent peroxisome degradation.9 Publications
