- | '''Tissue factor pathway inhibitor''' (TFPI) is a protease inhibitor which inhibits coagulation factor Xa and VIIa. 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 domain inhibits VIIa coagulation factor while Kunitz II domain inhibits Xa. | ||
