CC -!- FUNCTION: Required for cytoplasm to vacuole transport (Cvt) vesicles
CC formation and mitophagy. Involved in binding of
CC phosphatidylethanolamine to ATG8 and in recruitment of ATG8 and ATG5 to
CC the pre-autophagosomal structure. Protects ATG8 from ARG4-mediated
CC cleavage (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}. Vacuole membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Note=Vacuolar
CC and perivacuolar punctate structures. {ECO:0000250}.
CC -!- DOMAIN: Contains a beta-propeller domain involved in specific binding
CC to phosphatidylinositol 3,5-bisphosphate (PIP2). {ECO:0000250}.
CC -!- DOMAIN: The L/FRRG motif is essential for the cytoplasm to vacuole
CC transport (Cvt) pathway and for the recruitment of ATG8 and ATG16 to
CC the PAS in nutrient-rich medium and in both its recruitment to and
CC dissociation from the PAS under starvation conditions.
CC {ECO:0000250|UniProtKB:Q02887}.
CC -!- SIMILARITY: Belongs to the WD repeat PROPPIN family. {ECO:0000305}.
