| Specific Function
| fibrinolytic and fibrinogenolytic metalloproteinase that hydrolyzes the Aalpha-chain and more slowly the Bbeta-chain of fibrin and fibrinogen. Its fibrinolytic activity is direct, without any plasminogen activation. Also hydrolyzes casein and B-chain of oxidized insulin. Inhibits ADP-induced and collagen-induced platelet aggregation. Shows low hemorrhagic activity. Cleaves the plasma proteinase inhibitors alpha(2)-macroglobulin (A2M) and pregnancy zone protein (PZP), and is inhibited by them. The metalloprotease has no strict P1-P1' specificity requirement. Hydrolysis at sites with a Pro residue at P1 is observed with bradykinin, substance P, PZP and alpha chain fibrinogen (FGA) (PubMed:11910177).poor inhibitor of platelet aggregation. The disintegrin inhibits the adhesion of the alpha-4/beta-1 (ITGA4/ITGB1) integrin to VCAM-1. Inhibition on alpha-2b/beta-3 (ITGA2B/ITGB3) is low (By similarity). |
