ApoM is a 25 kDa plasma protein associated with high-density lipoproteins (HDLs). ApoM is important in the formation of pre-ss-HDL and also in increasing cholesterol efflux from macrophage foam cells [1]. Lipoproteins consist of lipids solubilized by apolipoproteins. ApoM lacks an external amphipathic motif and is uniquely secreted to plasma without cleavage of its terminal signal peptide [2].	Domain
