Betydelsefulla proteinkomponenter i plasma-VLDL, kylomikroner och en mindre fraktion av HDL, samt av återstående lipoproteiner efter lipoproteinlipasförmedlad, intravaskulär katabolism av triglyceridr ika lipoproteiner. Apolipoprotein E känns igen av LDL- och Apo E-receptorerna. Varje defekt i Apo E-metabolismen leder till ökade plasmahalter av Apo E. Det finns ett starkt samband mellan höga Apo E- nivåer och hyperlipoproteinemi typ III.
A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.
