CC -!- FUNCTION: Binds to membranes enriched in phosphatidylinositol 3-
CC phosphate (PtdIns(P3)) and phosphatidylinositol 4,5-bisphosphate
CC (PubMed:25882846). May be involved in several stages of intracellular
CC trafficking. {ECO:0000269|PubMed:25882846, ECO:0000305}.
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:25882846}.
CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle membrane
CC {ECO:0000305|PubMed:25882846}; Peripheral membrane protein
CC {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Early endosome membrane
CC {ECO:0000269|PubMed:25882846}; Peripheral membrane protein
CC {ECO:0000269|PubMed:25882846}; Cytoplasmic side
CC {ECO:0000269|PubMed:25882846}.
CC -!- DOMAIN: The PX domain mediates specific binding to membranes enriched
CC in phosphatidylinositol 3-phosphate (PtdIns(P3)).
CC {ECO:0000269|PubMed:25882846}.
CC -!- SIMILARITY: Belongs to the sorting nexin family. {ECO:0000305}.
