CC   -!- FUNCTION: The PI(3,5)P2 regulatory complex regulates both the synthesis
CC       and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2).
CC       Necessary for proper vacuole morphology. Plays an important role in
CC       osmotically-induced vacuole fragmentation. Required for cytoplasm to
CC       vacuole transport (Cvt) vesicle formation, pexophagy and starvation-
CC       induced autophagy. Involved in correct ATG9 trafficking to the pre-
CC       autophagosomal structure. Might also be involved in premeiotic DNA
CC       replication (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the PI(3,5)P2 regulatory complex. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Preautophagosomal structure membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Vacuole
CC       membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC       Endosome membrane {ECO:0000250}; Peripheral membrane protein
CC       {ECO:0000250}.
CC   -!- DOMAIN: The N-terminus might form a beta-propeller domain involved in
CC       specific binding to phosphatidylinositol 3,5-bisphosphate (PIP2),
CC       leading to the association of the protein to the membrane.
CC       {ECO:0000250}.
CC   -!- DOMAIN: The L/FRRG motif is essential for the cytoplasm to vacuole
CC       transport (Cvt) pathway, for the recruitment of ATG8 and ATG16 to the
CC       PAS in nutrient-rich medium, and for its recruitment to and
CC       dissociation from the PAS under starvation conditions.
CC       {ECO:0000250|UniProtKB:P43601}.
CC   -!- SIMILARITY: Belongs to the WD repeat PROPPIN family. {ECO:0000305}.
