CC   -!- FUNCTION: Component of the autophagy machinery that controls the major
CC       intracellular degradation process by which cytoplasmic materials are
CC       packaged into autophagosomes and delivered to lysosomes for
CC       degradation. Binds phosphatidylinositol 3-phosphate (PtdIns3P), and
CC       other phosphoinositides including PtdIns(3,5)P2, forming on membranes
CC       of the endoplasmic reticulum upon activation of the upstream ULK1 and
CC       PI3 kinases and is recruited at phagophore assembly sites where it
CC       regulates the elongation of nascent phagophores downstream of WIPI2.
CC       {ECO:0000250|UniProtKB:Q5MNZ6}.
CC   -!- SUBCELLULAR LOCATION: Preautophagosomal structure
CC       {ECO:0000250|UniProtKB:Q5MNZ6}. Lysosome
CC       {ECO:0000250|UniProtKB:Q5MNZ6}.
CC   -!- DOMAIN: The L/FRRG motif is required for recruitment to PtdIns3P.
CC       {ECO:0000250|UniProtKB:Q9Y4P8}.
CC   -!- SIMILARITY: Belongs to the WD repeat PROPPIN family. {ECO:0000305}.
