Tissue factor pathway inhibitor (TFPI) is also known as Extrinsic pathway inhibitor (EPI), Lipoprotein - associated coagulation inhibitor (LACI), is a plasma proteinase inhibitor synthesized by vascular endothelial cells and part of it is associated with glycosaminoglycans of these cells.
TFPI is a single-chain polypeptide which can reversibly inhibit Factor Xa (Xa) and Thrombin (Factor IIa).
TFPI is a secreted protein with a Nterminal acidic region, three Kunitz (K) domains separated with by two linker regions, and a Cterminal basic region.
The first K domain inhibits coagulation factor VIIa complexed to tissue factor (TF); The second K domain inhibits factor Xa; The third K domain binds to heparin; The Cterminal basic region may have several functions.
For example, it plays an important role in binding of TFPI to cell surfaces.
特徴
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 30.0 kDa.
The protein migrates as 41-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
