F10 - coagulation factor X Gene

Also known as fX; Cf10

About F10

Summary

This gene encodes factor X, a component of both the intrinsic and extrinsic blood coagulation pathways. The encoded protein is a zymogen that undergoes further processing in a vitamin K-dependent manner to generate mature factor X, a heterodimer comprised of disulfide-linked heavy and light chains. The mature factor X is proteolytically activated either by factor IXa (intrinsic pathway) or Factor VIIa (extrinsic pathway) to form Factor Xa serine endopeptidase. Activated Factor Xa catalyzes the conversion of prothrombin to Thrombin. A complete lack of the encoded protein is fatal to mice. A severe deficiency of the encoded protein in mice causes age-dependent iron deposition and cardiac fibrosis. Alternative splicing results in multiple transcript variants encoding different isoforms.
