Supplementary information

Apolipoprotein H (Apo-H) also known as β2-glycoprotein I functions mechanically as a plasma protein. It has a molecular weight of approximately 50 kDa and it is mostly expressed in the liver. Apo-H plays a role in the body's immune and coagulation systems binding to anionic surfaces such as phospholipids and preventing blood coagulation. Its ability to interact with negatively charged molecules makes it important in the modulation of the coagulation cascade helping maintain balance between bleeding and clotting.
Biological function summary

Apo-H acts as an anticoagulant and participates in the modulation of immune response. It forms complexes with lipid-bound proteins facilitating the clearance of these complexes from the bloodstream. This interaction is key in processes like platelet aggregation and stabilization of membranes. Apo-H also influences the removal of oxidized proteins and lipids reducing cellular stress and preventing tissue damage.

Pathways

Apo-H plays a critical role in the coagulation cascade and lipid metabolism. It interacts with proteins such as prothrombin and fibrinogen influencing blood coagulation pathways. Apo-H's involvement in the clearance of apoptotic cells integrates into the lipid metabolic pathway highlighting its relationship with apolipoproteins and other lipid-related proteins. These interactions illustrate the multi-functional aspects of Apo-H within these pathways.

Apo-H associates with antiphospholipid syndrome and cardiovascular diseases. These conditions arise from its role in coagulation and immune response where disruptions can lead to increased risk of thrombosis. The protein's interaction with other apolipoproteins such as Apo-A1 highlights possible implications in lipid metabolism disorders which in turn can exacerbate cardiovascular risk. Understanding these associations provides insights into potential therapeutic targets for treating these diseases.

General info

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.

Post-translational modifications

N- and O-glycosylated. PubMed:6587378 also reports glycosylation on 'Asn-188' for their allele.
