CC   -!- FUNCTION: Ubiquitin-like protein involved in cytoplasm to vacuole
CC       transport (Cvt), autophagy vesicles formation, mitophagy, and
CC       nucleophagy. Conjugation with ATG5 through a ubiquitin-like conjugating
CC       system involving also ATG7 as an E1-like activating enzyme and ATG10 as
CC       an E2-like conjugating enzyme, is essential for its function. The
CC       ATG12-ATG5 conjugate functions as an E3-like enzyme which is required
CC       for lipidation of ATG8 and ATG8 association to the vesicle membranes
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Forms a conjugate with ATG5. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Preautophagosomal structure membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ATG12 family. {ECO:0000305}.
