apolipoprotein B

Also found in: Acronyms, Encyclopedia, Wikipedia.

ap·o·lip·o·pro·tein B

an apolipoprotein found in chylomicrons, LDL, VLDL, and IDL. Elevated in the plasma of patients with familial hyperlipoproteinemia; it exists in two forms, B-100 and B-48.


A gene on chromosome 2p24-p23 that encodes apolipoprotein B, the main apoliprotein of chylomicrons and low-density lipoproteins, which appears in plasma as two main isoforms: apoB48 (which is synthesised exclusively in the gut) and apoB100 (which is synthesised in the liver).

Molecular pathology
APOB mutations cause hypobetalipoproteinaemia, normotriglyceridemic hypobetalipoproteinaemia, and hypercholesterolaemia due to ligand-defective apoB.

The other apolipoproteins were discovered by separation of the proteins after delipidation of plasma lipoproteins--initially classified as apolipoprotein A if present in [alpha]-lipoproteins (HDL), apolipoprotein B if in [beta]-lipoproteins (LDL), and apolipoprotein C if in pre-[beta]-lipoprotein (VLDL) (27).
