urokinase
A fibrinolytic enzyme involved in extracellular proteolysis; it is more active during cell migration and tissue remodeling, and cleaves fibronectin. See Kringle domain. Cf Streptokinase, Reteplase, tPA. McGraw-Hill Concise Dictionary of Modern Medicine. © 2002 by The McGraw-Hill Companies, Inc.
