| - | '''Tissue factor pathway inhibitor''' (TFPI) is a protease inhibitor which inhibits coagulation factor Xa and VIIa<ref>PMID:9112630</ref>. TFPI contains three Kunitz domains. The Kunitz domain is disulfide-rich and is arranged to form a twisted two-stranded antiparallel β sheet followed by an α helix. Kunitz I and II domains inhibit VIIa coagulation factor while Kunitz II domain inhibits Xa. | + | '''Tissue factor pathway inhibitor''' (TFPI) is a protease inhibitor which inhibits coagulation factor Xa and VIIa<ref>PMID:9112630</ref>.
