APOC4 (Apolipoprotein C-IV): APOC4 is a member of the apolipoprotein family, playing a role in lipid metabolism and transport. This protein is involved in the regulation of triglyceride-rich lipoprotein particles and may influence the interaction between lipoproteins and their receptors or lipid transfer proteins. APOC4 is present in various lipoprotein fractions in plasma, including very low-density lipoproteins (VLDL) and high-density lipoproteins (HDL). Its function in lipid metabolism suggests a potential involvement in the development of cardiovascular diseases and lipid disorders. Dysregulation or genetic variations of APOC4 can impact lipid levels and distribution, contributing to atherosclerosis, coronary artery disease, and other...
