Autophagy-related 7 (Atg7) encodes an E1-type ligase for the autophagic ubiquitin-like proteins encoded by Atg8a and Atg12. Its roles include autophagosome formation, maintaining neuromuscular function and normal lifespan.

Autophagy protein 5; Involved in autophagic vesicle formation. Conjugation with Atg12, through a ubiquitin-like conjugating system involving Atg7 as an E1-like activating enzyme and Atg10 as an E2-like conjugating enzyme, is essential for its function. The Atg12-Atg5 conjugate acts as an E3- like enzyme which is required for lipidation of Atg8 and its association to the vesicle membranes (By similarity).

Autophagy-related 16 (Atg16) encodes a protein that forms an E3-like protein complex. This complex contributes to the the covalent binding of the lipid phosphatidylethanolamine to the product of Atg8a, a key autophagy protein involved in autophagosome biogenesis. The product of Atg16 is involved in autophagosome biogenesis, maintenance of proper neuromuscular function, lifespan, ethanol sedation, and enteroendocrine cell function in the intestine.

Autophagy-related 3 (Atg3) encodes a protein involved in multiple autophagy processes such as autophagosome assembly, cellular response to starvation, and glycophagy.

Autophagy-related 8b, isoform A; Microtubule binding; protein tag; ubiquitin protein ligase binding; GABA receptor binding. It is involved in the biological process described with: macroautophagy; autophagosome maturation; cellular response to nitrogen starvation; autophagy of mitochondrion; autophagosome assembly.

Cysteine protease; Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy; Belongs to the peptidase C54 family.

Cysteine protease; Autophagy-related 4b (Atg4b) encodes a cysteine protease that cleaves the precursor product of Atg8a at the C-terminal region, thereby initiating autophagosome formation; Belongs to the peptidase C54 family.

Autophagy-related 8a (Atg8a) encodes a ubiquitin-like protein that is conjugated to phosphatidylethanolamine, and this lipid modification anchors it into the membrane of forming and completed autophagosomes. Atg8a product has roles in autophagosome formation, maintaining neuromuscular function and normal lifespan.

Phosphatidylinositol 3-kinase catalytic subunit type 3; Phosphotidylinositol 3 kinase 59F (Pi3K59F) encodes a lipid kinase that is required for formation of Phosphatidylinositol 3-phosphate. It functions in a core protein complex that includes the products of Atg6 and Vps15. It is involved in the control of vesicle trafficking, including autophagy, endocytosis and phagocytosis.
