| 1 | P02760 | Protein AMBP [Cleaved into: Alpha-1-microglobulin | 352 | "Inter-alpha-trypsin inhibitor inhibits trypsin, plasmin, and lysosomal granulocytic elastase. Inhibits calcium oxalate crystallization. ; Trypstatin is a trypsin inhibitor". | |
| 2 | Q96NZ8 | "WAP, Kazal, immunoglobulin, Kunitz and NTR domain-containing protein 1 " | 548 | Protease-inhibitor that contains multiple distinct protease inhibitor domains. Probably has serine protease- and metalloprotease-inhibitor activity (By similarity). | |
| 3 | P48307 | Tissue factor pathway inhibitor 2 | 235 | "May play a role in the regulation of plasmin-mediated matrix remodeling. Inhibits trypsin, plasmin, factor VIIa/tissue factor and weakly factor Xa. Has no effect on thrombin". | |
| 4 | O43291 | Kunitz-type protease inhibitor 2 | 252 | "Inhibitor of HGF activator. Also inhibits plasmin, plasma and tissue kallikrein, and factor XIa". | |
| 5 | Q8TEU8 | "WAP, Kazal, immunoglobulin, Kunitz and NTR domain-containing protein 2 " | 576 | "Protease-inhibitor that contains multiple distinct protease inhibitor domains. Probably has serine protease- and metalloprotease-inhibitor activity. Inhibits the biological activity of mature myostatin, but not activin (By similarity)". | |
| 6 | P10646 | Tissue factor pathway inhibitor | 304 | "Inhibits factor X (X(a)) directly and, in a Xa-dependent way, inhibits VIIa/tissue factor activity, presumably by forming a quaternary Xa/LACI/VIIa/TF complex. It possesses an antithrombotic action and also the ability to associate with lipoproteins in plasma". | |
| 7 | O43278 | Kunitz-type protease inhibitor 1 | 529 | Inhibitor of HGF activator. Also acts as an inhibitor of matriptase (ST14). |
