GtoPdb Ligand ID: 11181

Comment: TFPI is a serine protease inhibitor that regulates the tissue factor (TF)-dependent blood coagulation pathway (extrinsic pathway). It inhibits activated factor X (Xa) and VIIa-TF proteases in an autoregulatory loop. Some isoforms are tethered to the cell membrane by expression of a glycosylphosphatidylinositol (GPI) anchor, others isoforms are secreted [1-2]. Inhibition of the TFPI restores hemostasis, which is a mechanism being exploited for therapeutic benefit in inherited bleeding disorders.
