Fibrinogen is cleaved by another protein, thrombin, exposing knobs A and B to form fibrin. The fibrin forms clots to prevent excessive bleeding from wounds sustained. Clotting factors, like factor XIII, are often linked to fibrin. 3D Printed Physical Model of Fibrinogen Shown below is a 3D printed physical model of Fibrinogen. The structure is shown as an alpha carbon backbone colored by chain, with the three chains of each copy of fibrinogen colored yellow, blue and purple.
