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|UniProtKB:Q2XPP5}.
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   -!- PTM: The C-terminal 2 residues are removed by ATG4 to expose Gly-117 at
CC       the C-terminus. The C-terminal Gly is then amidated with
CC       phosphatidylethanolamine by an activating system similar to that for
CC       ubiquitin. {ECO:0000250|UniProtKB:P38182}.
CC   -!- SIMILARITY: Belongs to the ATG8 family. {ECO:0000305}.
