Apolipoprotein E acts as a ligand for low-density receptors and participates in the transport and redistribution of cholesterol and other lipids. Other functions include immune regulation and cell growth regulation and differentiation. It is believed that Apo E is involved in tissue repair because of the increased protein content found in the areas of peripheral nerve injury and regeneration. The mutant form is associated with familial type III hyperlipoproteinemia. The concentration of Apo E in normal plasma is 5 mg per 100 ml. In addition to promoting lipid solubilization, these proteins also help maintain the structural integrity of lipoproteins, act as ligands for lipoprotein receptors, and regulate the activity of enzymes involved in lipid metabolism. Large amounts of ApoE are produced in the liver and brain and in almost every organ. ApoE is an important component of all plasma lipoproteins. It interacts with specific ApoE receptors, allowing liver cells to take up chylomicron residues, which is an essential step in the process of normal lipid metabolism. It also binds to the LDL receptor (Apo B/E). The deficiency of ApoE is the cause of type III hyperlipoproteinemia. There are three main isoforms of ApoE. E2, E3 and E4, the difference between them is only one amino acid substitution.
