NCIt synonyms : PIVKA-II; DCP; Protein Induced by Vitamin K Absence/Antagonist-II; Protein Induced by Vitamin K Absence-II; Protein Induced by Vitamin K Absence or Antagonist II; Des-Gamma-Carboxy Prothrombin;
NCIt definition : Des-gamma carboxyprothrombin (622 aa, 70 kDa) is encoded by the human F2 gene. This
protein is involved in blood coagulation. This form of prothrombin is not efficiently
converted to the active enzyme thrombin because it lacks gamma-carboxyglutamyl residues.
These modified glutamyl residues are absent because of either vitamin K deficiency
or inhibition of vitamin K activity that, in turn, inhibits the enzyme that carboxylates
these residues, vitamin K-dependent gamma-carboxylase.;
NCIt note : Des-gamma carboxyprothrombin is used in Japan as a biomarker for hepatocellular carcinoma.;
