Apolipoprotein M is an apolipoprotein and member of the lipocalin protein family that in humans is encoded by the APOM gene.[5][6][7] It is found associated with high density lipoproteins and to a lesser extent with low density lipoproteins and triglyceride-rich lipoproteins. The encoded protein is secreted through the plasma membrane but remains membrane-bound, where it is involved in lipid transport. Two transcript variants encoding two different isoforms have been found for this gene, but only one of them has been fully characterized.[7] It lacks an external amphipathic motif and is uniquely secreted to plasma without cleavage of its terminal signal peptide.[8] The average molecular weight is 21253 Da, and the monoisotopic molecular weight is 21239 Da.
