DescriptionApolipoprotein B, human
OverviewTwo forms of Apo B exist: Apo B-100 and Apo B-48. The first is found in VLDL and LDL and is produced by the liver. The second is found in chylomicrons and originates in the intestine.

Apo B is purified from LDL isolated by density gradient ultracentrifugation (1.03-1.05 g/mL density range) followed by size exclusion chromatography in 10 mM deoxycholate, 50 mM NaCl, 50 mM Na2CO3, pH 10 (Walsh & Atkinson 1983).

PROPERTIES:

Apo B, which has a Mr of 550 kD, is the major protein found in LDL and is responsible for the cellular uptake of LDL particles from the plasma (Goldstein & Brown 1982). The Apo B prepared by this procedure is aggregated. The aggregates are not retained by a 0.45 mm filter, but migrate only a short distance into a 5% SDS PAGE gel. In the isolation buffer, Apo B gives a stable solution that is slightly hazy.

Entrez Gene Number
Entrez Gene SummaryThis gene product is the main apolipoprotein of chylomicrons and low density lipoproteins. It occurs in plasma as two main isoforms, apoB-48 and apoB-100: the former is synthesized exclusively in the gut and the latter in the liver. The intestinal and the hepatic forms of apoB are encoded by a single gene from a single, very long mRNA. The two isoforms share a common N-terminal sequence. The shorter apoB-48 protein is produced after RNA editing of the apoB-100 transcript at residue 2180 (CAA->UAA), resulting in the creation of a stop codon, and early translation termination.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P04114 # Apolipoprotein B is a major protein constituent of chylomicrons (apo B-48), LDL (apo B-100) and VLDL (apo B-100). Apo B-100 functions as a recognition signal for the cellular binding and internalization of LDL particles by the apoB/E receptor.
SIZE: 4563 amino acids; 515563 Da
SUBCELLULAR LOCATION: Secreted.
PTM: Palmitoylated; structural requirement for proper assembly of the hydrophobic core of the lipoprotein particle.
DISEASE: SwissProt: P04114 # Defects in APOB are a cause of familial hypobetalipoproteinemia (FHBL) [MIM:107730]. FHBL is a genetically heterogeneous autosomal co-dominant disorder, associated with reduced plasma concentrations of apoB, LDL and VLDL. Heterozygotes for FHBL are usually asymptomatic with LDL cholesterol and apoB- 100 concentrations less than 50% of those in normal plasma. Homozygotes have extremely low plasma LDL cholesterol and apoB-100 concentrations, and clinical presentation may vary from no symptoms to severe gastrointestinal and neurological dysfunction similar to abetalipoproteinemia [MIM:200100]. & Defects in APOB are a cause of familial ligand-defective apolipoprotein B-100 (FDB) [MIM:144010]. FDB is a dominantly inherited disorder of lipoprotein metabolism leading to hypercholesterolemia and increased proneness to coronary artery disease (CAD). The plasma cholesterol levels are dramatically elevated due to impaired clearance of LDL particles by defective APOB/E receptors. & Defects in APOB associated with defects in other genes (polygenic) can contribute to hypocholesterolemia.SIMILARITY:SwissProt: P04114 ## Contains 1 vitellogenin domain.

Storage and Shipping Information
Storage ConditionsMaintain lyophilized material at <= -20°C for up to six months. Reconstitute to 1 mL by adding deionized water. If the deoxycholate is removed, Apo B-100 will slowly aggregate and become insoluble. After reconstitution maintain at +2-8°C for up to 4 weeks.
