Background: Coagulation Factor X

As the only known physiological activator of thrombin, Factor X is a vitamin K-dependent plasma protease that plays a pivotal role in blood coagulation. Human Factor X is initially synthesized in the liver as a single-chain precursor of 488 amino acid residues with a signal peptide and a pro region (residues 1‑40). Both the intrinsic and extrinsic pathways activate Factor X to Xa, which consists of light (residues 41‑179) and heavy (residues 235‑488) chains linked by a disulfide bond. The light chain contains a Gla and two EGF‑like domains and the heavy chain corresponds to the serine protease domain. The full-length human Factor X was expressed and the pro enzyme was purified and activated. The active protease (rhFactor Xa) was further purified and analyzed for its activity towards either peptides or proteins containing a Xa cleavage site. In addition to the activity described in the Activity Assay Protocol, rhFactor Xa also can be used to cleave fusion proteins containing a Factor Xa cleavage site. The conditions for the optimal cleavage of a particular fusion protein, such as the molar ratio between rhFXa and the protein and time and temperature of incubation, are protein-dependent and need to be individually determined.
