WebFibrin formation involves cleavage of FpA (orange) by thrombin (fibrin I), which polymerizes into protofibrils. Subsequently, FpB (green) is cleaved by thrombin (fibrin II). FpB cleavage is associated with release of the C-terminal α-domains, which interact for lateral aggregation. Web23 de jul. de 2024 · Fibrin (also called Factor Ia) is a fibrous, non-globular protein involved in the clotting of blood. It is formed by the action of the protease thrombin on fibrinogen, which causes it to polymerize. The polymerized fibrin, together with platelets, forms a hemostatic plug or clot over a wound site.
