CC   -!- FUNCTION: Participates in the reverse transport of cholesterol from
CC       tissues to the liver for excretion by promoting cholesterol efflux from
CC       tissues and by acting as a cofactor for the lecithin cholesterol
CC       acyltransferase (LCAT). As part of the SPAP complex, activates
CC       spermatozoa motility.
CC   -!- SUBUNIT: Homodimer (By similarity). Interacts with APOA1BP and CLU.
CC       Component of a sperm activating protein complex (SPAP), consisting of
CC       APOA1, an immunoglobulin heavy chain, an immunoglobulin light chain and
CC       albumin. Interacts with NDRG1. Interacts with SCGB3A2 (By similarity).
CC       Interacts with NAXE and YJEFN3 (By similarity).
CC       {ECO:0000250|UniProtKB:G5BQH5, ECO:0000250|UniProtKB:P02647,
CC       ECO:0000250|UniProtKB:P04639}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Major protein of plasma HDL, also found in
CC       chylomicrons.
CC   -!- PTM: Glycosylated. {ECO:0000250}.
CC   -!- PTM: Palmitoylated. {ECO:0000250}.
CC   -!- PTM: Phosphorylation sites are present in the extracellular medium.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the apolipoprotein A1/A4/E family.
CC       {ECO:0000305}.
