Related Product Information for
anti-APOH antibody
Apolipoprotein-H, also known as beta2-Glycoprotein I (beta2GPI), is a plasma glycoprotein that circulates at a concentration of 200 ug/ml (4 uM). Synthesized in the liver, beta2GPI is a single chain molecule of 48 kDa, consisting of five repeating internally disulphide-bonded structures referred to as sushi domains. Relative to other glycoproteins, beta2GPI has an unusually high content of cysteine (6.2%), proline (8.3%) and carbohydrate (19%). Almost half the circulating beta2GPI in plasma is associated with lipoproteins of all major fractions. beta2GPI has been demonstrated to bind negatively charged phospholipids, heparin and platelets. Although the precise function(s) are as yet unknown, beta2GPI has been demonstrated to interfere with blood coagulation by competitively binding to negatively charged phospholipid surfaces exposed during cell activation or damage. Recent evidence also implicates beta2GPI as a cofactor recognized by anti-phospholipid antibodies present in some autoimmune disorders such as systemic lupus erythematosus (SLE)1-3.

NCBI Summary for APOH
Apolipoprotein H has been implicated in a variety of physiologic pathways including lipoprotein metabolism, coagulation, 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, but it does not seem to be required for the reactivity of antiphospholipid autoantibodies associated with infections.

UniProt Comments for APOH
Function: 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.

Subcellular location: Secreted.

Tissue specificity: Expressed by the liver and secreted in plasma.

Post-translational modification: N- and O-glycosylated. Ref.10 also reports glycosylation on 'Asn-188' for their allele. Ref.10 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21

Sequence similarities: Contains 4 Sushi (CCP/SCR) domains.
