CC -!- FUNCTION: Ubiquitin-like modifier involved in autophagosomes formation.
CC May mediate the delivery of the autophagosomes to the vacuole via the
CC microtubule cytoskeleton. {ECO:0000250|UniProtKB:P38182}.
CC -!- SUBUNIT: Interacts with ATG4. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, autophagosome membrane
CC {ECO:0000250|UniProtKB:P38182}; Lipid-anchor
CC {ECO:0000250|UniProtKB:P38182}. Vacuole membrane
CC {ECO:0000250|UniProtKB:P38182}; Lipid-anchor
CC {ECO:0000250|UniProtKB:P38182}. Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:Q8LEM4}.
CC -!- TISSUE SPECIFICITY: Constitutively expressed.
CC {ECO:0000269|PubMed:15494556}.
CC -!- PTM: The C-terminal 4 residues are removed by ATG4 to expose Gly-117 at
CC the C-terminus. This Gly-117 forms then a thioester bond with the 'Cys-
CC 558' of ATG7 (E1-like activating enzyme) before being transferred to
CC the 'Cys-258' of ATG3 (the specific E2 conjugating enzyme), in order to
CC be finally amidated with phosphatidylethanolamine. This lipid
CC modification anchors ATG8 to autophagosomes.
CC {ECO:0000250|UniProtKB:P38182}.
CC -!- SIMILARITY: Belongs to the ATG8 family. {ECO:0000305}.
