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 (By similarity). {ECO:0000250}.
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 -!- MASS SPECTROMETRY: [Apolipoprotein A-I]: Mass=28166;
CC Method=Electrospray; Evidence={ECO:0000269|PubMed:21298813};
CC -!- SIMILARITY: Belongs to the apolipoprotein A1/A4/E family.
CC {ECO:0000305}.
