FENTON n Wadsworth Center for Laboratories & Research, New York State Department of Health, Empire State Plaza, Box 509, Albany, NY 12201, and Department of Physiology, The Albany Medical College of Union University, Albany, NY 12208, USA INTRODUCTION Thrombin (EC 3. 4. 21. 5) is the activation product of its blood-circulating or cellular-sequestered zymogen, prothrombin. Unlike the majority of enzymes and activated proteins of the blood-coagulation, fibrinolytic, and complement systems, thrombin has multiple bioregulatory functions, which are central in hemostasis, wound 1 6 healing, and perhaps developmental, as well as certain disease processes. - Hemostasis occurs at three levels, which are: i) plasma proteins (e. g. , coagulation factors V, VIII, and IX; proteins C and S, complement components), ii) blood cells (e. g. , platelets, monocytes, neutrophils), and iii) blood vessels (e. g. , endothelium, smooth muscles). Moreover, thrombin functions at all three levels of hemostasis, while the majority of cell types known are responsive to greater or lesser extents to thrombin. Thrombin furthermore functions both as a proteolytic enzyme with arginine- or lysine-directed specificities or as a nonenzymic activated protein 1 6 (hormone-like) involving receptor occupancy on certain cells.
