Tissue factor pathway inhibitor (or TFPI) is a single-chain polypeptide which can reversibly inhibit
FVIIa-tissue factor
complex.
TFPI contributes significantly to the inhibition of Xa in vivo, despite being present at concentrations of only 2.5 nM.
Genetics
The gene for TFPI is located on chromosome 2q31-q32.1, and has nine exons which span 70 kb. A similar gene, termed retinal pigment epithelial cell growth-promoting properties.
Protein structure
TFPI has a relative molecular mass of 34,000 to 40,000 depending on the degree of proteolysis of the C-terminal region.
TFPI consists of a highly negatively charged amino-terminus, three tandemly linked
basic pancreatic trypsin inhibitor
.
