| Tissue Specificity | Detected in blood plasma (at protein level). Synthesized primarily in the liver and secreted in plasma. |
| Post Translational Modifications | Activated by factor XIa, which excises the activation peptide. The propeptide can also be removed by snake venom protease. The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains. |
| Function | Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa. |
