Summaries for APOB Gene

Entrez Gene Summary for APOB Gene

  • 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.

GeneCards Summary for APOB Gene

APOB (Apolipoprotein B) is a Protein Coding gene. Diseases associated with APOB include hypobetalipoproteinemia and hypercholesterolemia, due to ligand-defective apo b. Among its related pathways are Signaling by GPCR and Platelet homeostasis. GO annotations related to this gene include binding and heparin binding.

UniProtKB/Swiss-Prot for APOB Gene

  • 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
