Apolipoprotein D (apoD) is a lipocalin that binds lipids and steroid hormones. The apoD gene is expressed in many tissues, e.g. brain, testis, adrenal gland, kidney, placenta, spleen, lung, and pancreas. ApoD likely functions as a transporter of lipids or lipid hormones, and is involved in the interaction between HDL and LDL. ApoD gene polymorphisms are associated with obesity, hyperinsulinemia, and type 2 diabetes. Normal concentration of apoD in human plasma is approximately 0.05-0.15 g/L.
