Function
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)[1].
Disease
Overexpression of FIa can cause thrombosis.
