[[Fibrin]] (or Factor Ia, FIa) is a fibrous protein which when polymerized is involved in blood clotting. The polymerization epitopes of FIa are called A-knob and B-knob. [[Fibrinogen]] (Factor I, FI) is converted by thrombin to fibrin. Limited proteolysis of FI results in a fragment named D which when cross-linked by factor XIII is called double-D FIa (DDFIa) | [[Fibrin]] (or Factor Ia, FIa) is a fibrous protein which when polymerized is involved in blood clotting.
