UniProt Comments
Cysteine protease required for autophagy, which is able to cleave the C-terminal part of ATG8 that may be subsequently converted to a smaller form, with a revealed C-terminal glycine. ATG8 is then activated by ATG7 and is subsequently attached to ATG3, another E2-like enzyme, after which the C-terminal glycine of ATG8 is conjugated to phosphatidylethanolamine by an amide bond. This conjugated form has the capacity for the binding to autophagosomes.
