CC -!- FUNCTION: APOE is an apolipoprotein, a protein associating with lipid
CC particles, that mainly functions in lipoprotein-mediated lipid
CC transport between organs via the plasma and interstitial fluids. APOE
CC is a core component of plasma lipoproteins and is involved in their
CC production, conversion and clearance. Apoliproteins are amphipathic
CC molecules that interact both with lipids of the lipoprotein particle
CC core and the aqueous environment of the plasma. As such, APOE
CC associates with chylomicrons, chylomicron remnants, very low density
CC lipoproteins (VLDL) and intermediate density lipoproteins (IDL) but
CC shows a preferential binding to high-density lipoproteins (HDL). It
CC also binds a wide range of cellular receptors including the LDL
CC receptor/LDLR and the very low-density lipoprotein receptor/VLDLR that
CC mediate the cellular uptake of the APOE-containing lipoprotein
CC particles (By similarity). Finally, APOE has also a heparin-binding
CC activity and binds heparan-sulfate proteoglycans on the surface of
CC cells, a property that supports the capture and the receptor-mediated
CC uptake of APOE-containing lipoproteins by cells (PubMed:23676495).
CC {ECO:0000250|UniProtKB:P02649, ECO:0000269|PubMed:23676495}.
CC -!- SUBUNIT: Homotetramer (By similarity). May interact with ABCA1;
CC functionally associated with ABCA1 in the biogenesis of HDLs (By
CC similarity). May interact with APP/A4 amyloid-beta peptide; the
CC interaction is extremely stable in vitro but its physiological
CC significance is unclear (By similarity). May interact with MAPT (By
CC similarity). May interact with MAP2. In the cerebrospinal fluid,
CC interacts with secreted SORL1 (By similarity).

CC -!- INTERACTION:
CC P08226; Q9QZM3: Clcf1; NbExp=2; IntAct=EBI-1634131, EBI-3454258;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P02649}.
CC Secreted, extracellular space {ECO:0000250|UniProtKB:P02649}. Secreted,
CC extracellular space, extracellular matrix
CC {ECO:0000250|UniProtKB:P02649}. Note=In the plasma, APOE is associated
CC with chylomicrons, chylomicrons remnants, VLDL, LDL and HDL
CC lipoproteins. Lipid poor oligomeric APOE is associated with the
CC extracellular matrix in a calcium- and heparan-sulfate proteoglycans-
CC dependent manner. Lipidation induces the release from the extracellular
CC matrix. {ECO:0000250|UniProtKB:P02649}.
CC -!- PTM: APOE exists as multiple glycosylated and sialylated glycoforms
CC within cells and in plasma. The extent of glycosylation and sialylation
CC are tissue and context specific. {ECO:0000269|PubMed:29516132}.
CC -!- PTM: Glycated in plasma VLDL. {ECO:0000250|UniProtKB:P02649}.
CC -!- PTM: Phosphorylated by FAM20C in the extracellular medium.
CC {ECO:0000250|UniProtKB:P02649}.
CC -!- DISRUPTION PHENOTYPE: APOE knockout mice display severe
CC hypercholesterolemia associated with impaired clearance of dietary fats
CC (PubMed:1423598). Excess cholesterol is more particularly associated
CC with the atherogenic very low and intermediate density lipoproteins in
CC the plasma (PubMed:1423598). These mice are therefore prone to
CC atherosclerosis (PubMed:1423598). Mice lacking both Cx3cr1 and Apoe
CC show decreased atherogenesis (PubMed:12569158). Animals with a double
CC knockout of APOE and CD36, fed a Western diet for 12 weeks, exhibit
CC much lower levels of CXCL1, CXCL2 and CCL5 mRNA expression in the
CC descending aorta and a corresponding decrease in atherosclerotic lesion
CC formation, compared to APOE single knockout mice (PubMed:23812099).
CC Animals with a double knockout of APOE and TLR4 or TLR6 also have less
CC aortic plaque formation than single knockout mice. All 3 double
CC knockout show lower serum concentrations of IL1A, ILB and IL18
CC (PubMed:20037584). {ECO:0000269|PubMed:12569158,
CC ECO:0000269|PubMed:1423598, ECO:0000269|PubMed:20037584,
CC ECO:0000269|PubMed:23812099}.
CC -!- SIMILARITY: Belongs to the apolipoprotein A1/A4/E family.
