CC -!- FUNCTION: Ubiquitin-like modifier involved in autophagosomes formation.
CC With ATG4, mediates the delivery of the autophagosomes to the vacuole
CC via the microtubule cytoskeleton. Required for selective autophagic
CC degradation of the nucleus (nucleophagy) as well as for mitophagy which
CC contributes to regulate mitochondrial quantity and quality by
CC eliminating the mitochondria to a basal level to fulfill cellular
CC energy requirements and preventing excess ROS production. Participates
CC also in membrane fusion events that take place in the early secretory
CC pathway. Also involved in endoplasmic reticulum-specific autophagic
CC process and is essential for the survival of cells subjected to severe
CC ER stress. The ATG8-PE conjugate mediates tethering between adjacent
CC membranes and stimulates membrane hemifusion, leading to expansion of
CC the autophagosomal membrane during autophagy.
CC {ECO:0000250|UniProtKB:P38182}.
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}.
CC -!- PTM: The C-terminal 2 residues are removed to expose Gly-116 at the C-
CC 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}.
