Fibrin is the protein involved in the formation of a blood clot. When there is an injury, a series of reactions occur in the blood that lead to the formation of fibrin, which sticks to the platelets and forms a clot to stop the bleeding. Keratin, actin, and myosin are all structural proteins found in different types of cells, but they are not involved in blood clotting.
