Fibrin Formation

Fibrin formation is a critical biochemical process in blood coagulation, resulting in the transformation of soluble fibrinogen into insoluble fibrin strands that form the structural basis of a blood clot. This process is essential for hemostasis (the cessation of bleeding) and plays a central role in wound healing and thrombosis. The process begins with the activation of thrombin, a serine protease that cleaves fibrinogen to form fibrin monomers. These monomers polymerize to form protofibrils, which aggregate into thicker fibers, creating a three-dimensional network. Fibrin formation is regulated by thrombin concentration and environmental factors, and genetic variants can influence its dynamics. Abnormal regulation can lead to excessive or insufficient clotting, impacting hemostasis and thrombosis. Fibrinogen is encoded by three genes (*FGA*, *FGB*, *FGG*) clustered on human chromosome 4.
