Apolipoprotein C3 (ApoC3)

Target
ApoC3
Molecular classification
Apolipoprotein
01

Overview

Apolipoprotein C3 (ApoC3) is a small apolipoprotein primarily produced by the liver and small intestine. It inhibits lipoprotein lipase (LPL) and hepatic lipase, thereby delaying the clearance of triglyceride-rich particles from the bloodstream. Elevated ApoC3 levels are associated with hypertriglyceridemia and increased cardiovascular risk. It promotes assembly and secretion of VLDL particles from hepatocytes under lipid-rich conditions, with recent evidence suggesting an intracellular function for ApoC3.
