Factor IX is produced as a zymogen, an inactive precursor. It is processed to remove the signal peptide, glycosylated and then cleaved by factor XIa (of the contact pathway) or factor VIIa (of the tissue factor pathway) to produce a two-chain form, where the chains are linked by a disulfide bridge. When activated into factor IXa, in the presence of Ca , membrane phospholipids, and a Facto… WebFactor IX is a key component of the plasma system that forms a fibrin clot at a site of vascular injury.
