Recombinant Human APOB, His-tagged

• Cat.No.: APOB-27149TH
• Product Overview: Recombinant fragment, corresponding to amino acids 1406-1606 of Human Apolipoprotein B, fused to a His tag at N-terminal end, 31kDa.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 1406-1606 a.a.
• Description: This 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. Mutations in this gene or its regulatory region cause hypobetalipoproteinemia, normotriglyceridemic hypobetalipoproteinemia, and hypercholesterolemia due to ligand-defective apoB, diseases affecting plasma cholesterol and apoB levels.
