Human APOM Recombinant Protein

ApoM (apolipoprotein M) is an apolipoprotein and member of the lipocalin protein family. The lipocalins share limited regions of sequence homology and a common tertiary structure architecture. They have an eight-stranded; antiparallel; symmetrical _-barrel fold; which is in essence a beta sheet which has been rolled into a cylindrical shape. Inside this barrel is located a ligand binding site. They transport small hydrophobic molecules such as steroids; bilins; retinoids; and lipids. Lipocalins have been associated with many biological processes; among them immune response; pheromone transport; biological prostaglandin synthesis; retinoid binding; and cancer cell interactions. Lipocalins are comparatively small in size; and are thus less complicated to study as opposed to large; bulky proteins. They can also bind to various ligands for different biological purposes. ApoM is associated with high density lipoproteins and to a lesser extent with low density lipoproteins and triglyceride-rich lipoproteins. ApoM is involved in lipid transport and can bind sphingosine-1-phosphate; myristic acid; palmitic acid and stearic acid; retinol; all-trans-retinoic acid and 9-cis-retinoic acid.
