Autophagy-related Protein 9A, APG9-like 1, Cytoplasm to Vacuole Targeting Protein 7, Autophagy-related Protein 9, APG9A

Survival of environmental stress conditions requires the maintenance of cellular homeostasis. To preserve this balance, cells utilize a degradative mechanism known as autophagy. During this process, in response to starvation or other stresses, bulk cytoplasm is non-specifically sequestered within double-membrane vesicles and delivered to the lysosome/vacuole for subsequent degradation and recycling. Atg9 is the only integral membrane protein required for autophagosome formation and considered a membrane carrier in autophagy-related pathways.
