CC -!- SUBUNIT: Homotetramer. May interact with ABCA1; functionally associated
CC with ABCA1 in the biogenesis of HDLs. May interact with APP/A4 amyloid-
CC beta peptide; the interaction is extremely stable in vitro but its
CC physiological significance is unclear. May interact with MAPT. May
CC interact with MAP2. In the cerebrospinal fluid, interacts with secreted
CC SORL1. Interacts with PMEL; this allows the loading of PMEL luminal
CC fragment on ILVs to induce fibril nucleation.
CC {ECO:0000256|ARBA:ARBA00034326}.
CC -!- SUBCELLULAR LOCATION: Endosome, multivesicular body
CC {ECO:0000256|ARBA:ARBA00004559}. Extracellular vesicle
CC {ECO:0000256|ARBA:ARBA00034305}. Secreted, extracellular space
CC {ECO:0000256|ARBA:ARBA00004239}. Vesicle
CC {ECO:0000256|ARBA:ARBA00004373}.
CC -!- SIMILARITY: Belongs to the apolipoprotein A1/A4/E family.
CC {ECO:0000256|ARBA:ARBA00008788}.
