Apolipoprotein D
| View/Edit Human | View/Edit Mouse |
Apolipoprotein D is a protein that in humans is encoded by the APOD gene.[3][4][5] Unlike other lipoproteins, which are mainly produced in the liver, apolipoprotein D is mainly produced in the brain and testes.[6]
Function
Apolipoprotein D (Apo-D) is a component of high-density lipoprotein that has no marked similarity to other apolipoprotein sequences. It has a high degree of homology to plasma retinol-binding protein and other members of the alpha 2 microglobulin protein superfamily of carrier proteins, also known as lipocalins. It is a glycoprotein of estimated molecular weight 33 KDa. Apo-D is closely associated with the enzyme lecithin:cholesterol acyltransferase - an enzyme involved in lipoprotein metabolism.[5] ApoD has also been shown to be an important link in the transient interaction between HDL and LDL particles and between HDL particles and cells.[7]
Clinical significance
APOD is a biomarker of androgen insensitivity syndrome (AIS). APOD is an androgen up-regulated gene in normal scrotal fibroblast cells in comparison to CAIS labia majora cells.[8]
APOD is associated with neurological disorders and nerve injury, especially related to myelin sheath. APOD was shown to be elevated in a rat model of stroke.[6] APOD is elevated in patients with schizophrenia, bipolar disorder, and Alzheimer's disease.[6]
