Apo CII contains 78 amino acid residues. The m.w. is 8.5 kDa (Jackson et al., 1977).
The lipid-binding domain of Apo CII is localized to a region in the N-terminal with a strongly amphipathic nature (Macphee et al., 1999). Apo CII is also one of the key components of the metabolism of total triacylglycerol-rich lipoproteins by activating lipoprotein lipase that hydrolyzes fatty acids from triacylglycerols in chylomicrons (Kei et al., 2012).
