ApoA-IV Protein plays a vital role in lipid metabolism, influencing chylomicron and VLDL secretion and catabolism. It efficiently activates lipoprotein lipase with ApoC-II and serves as a potent activator of LCAT. As a component of HDL and chylomicrons, ApoA-IV is integral to cholesterol transport and metabolism. Structurally, the protein forms homodimers, reflecting its crucial role in lipid-related processes. ApoA-IV Protein, Mouse (P.pastoris, His) is the recombinant mouse-derived ApoA-IV protein, expressed by P. pastoris , with N-6*His labeled tag.
