Apolipoprotein H, also known as beta-2-glycoprotein I, is a component of circulating plasma lipoproteins. It has been implicated in a variety of physiologic pathways including lipoprotein metabolism, coagulation, hemostasis, and the production of antiphospholipid autoantibodies. APOH may be a required cofactor for anionic phospholipid binding by the antiphospholipid autoantibodies found in sera of many patients with lupus and primary antiphospholipid syndrome (APS). The anti-beta (2) glycoprotein I antibodies from APS patients, mediate inhibition of activated protein C which has anticoagulant properties. Because beta-2-GPI is the main autoantigen in patients with APS, the disruption of this pathway by autoantibodies may be an important mechanism for thrombosis in patients with APS.[provided by RefSeq, Dec 2019]
GeneCards Summary for APOH Gene
APOH (Apolipoprotein H) is a Protein Coding gene. Diseases associated with APOH include Antiphospholipid Syndrome and Syphilis. Among its related pathways are Response to elevated platelet cytosolic Ca2+ and Statin Pathway. Gene Ontology (GO) annotations related to this gene include identical protein binding and heparin binding. An important paralog of this gene is CR2.
UniProtKB/Swiss-Prot Summary for APOH Gene
Binds to various kinds of negatively charged substances such as heparin, phospholipids, and dextran sulfate. May prevent activation of the intrinsic blood coagulation cascade by binding to phospholipids on the surface of damaged cells.
