CC   -!- FUNCTION: Ubiquitin-like protein involved in autophagy vesicles
CC       formation. 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 acts as an E3-like enzyme which is required for
CC       lipidation of ATG8 family proteins and their association to the vesicle
CC       membranes. The ATG12-ATG5 conjugate also regulates negatively the
CC       innate antiviral immune response by blocking the type I IFN production
CC       pathway through direct association with RARRES3 and MAVS. Also plays a
CC       role in translation or delivery of incoming viral RNA to the
CC       translation apparatus (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Forms a conjugate with ATG5. The ATG12-ATG5 conjugate forms a
CC       complex with several units of ATG16L1. Forms an 800-kDa complex
CC       composed of ATG12-ATG5 and ATG16L2 (By similarity). Interacts with
CC       ATG3, ATG7 and ATG10. ATG12-ATG5 also interacts with MAVS, MGA, RARRES3
CC       and TECPR1 (By similarity). {ECO:0000250|UniProtKB:O94817,
CC       ECO:0000250|UniProtKB:Q9CQY1}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Preautophagosomal
CC       structure membrane {ECO:0000250}; Peripheral membrane protein
CC       {ECO:0000250}. Note=TECPR1 recruits the ATG12-ATG5 conjugate to the
CC       autolysosomal membrane. {ECO:0000250}.
CC   -!- DOMAIN: Shares weak sequence similarity with ubiquitin family, but
CC       contains an 'ubiquitin superfold' and the C-terminal Gly is required
CC       for isopeptide linkage. {ECO:0000250}.
CC   -!- PTM: Acetylated by EP300. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ATG12 family. {ECO:0000305}.
