Secondary Information

Protein Function fibrin polymerization and cross-linking, role in the initiation of fibrinolysis, binding and regulation of factor XIII activity, interactions with platelets and other cells, and role in mediating thrombin binding to fibrin, a thrombin inhibitory function termed ‘antithrombin I
Biochemical Properties Aα, Bß, and γ are joined by five symmetrical disulfide bridges; C-terminal region of each fibrinogen or fibrin γ chain contains a single cross-linking site at which factor XIII or XIIIa catalyzes the formation of γ dimers
Significance in milk Acute phase proteins; potential marker of mastitis
