Thrombin-like snake venom serine protease that clots fibrinogen (FGA) by releasing fibrinopeptide A. According to PubMed:8585090, only cleaves rabbit fibrinogen, whereas no specificity is described in PubMed:3910643 (tests done on bovine fibrinogen). Also acts as a C3 convertase that independently cleaves human C3 and kick-starts the complement cascade. Also increases urokinase-type plasminogen activator (PLAU) and plasminogen activator inhibitor (SERPINE1) in cultured bovine pulmonary artery endothelial cells. Dose-dependently inhibits collagen-induced platelet aggregation. Source: Recombinant protein corresponding to aa25-260 from Protobothrops flavoviridis Thrombin-like enzyme flavoxobin, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E.coli.
