SERPINE2 (Serpin Family E Member 2): SERPINE2 is a serine protease inhibitor, also known as protease nexin-1, that plays a key role in regulating proteolytic pathways in the body. It is involved in tissue remodeling, fibrinolysis, and neuronal growth, and helps inhibit enzymes such as thrombin and urokinase-type plasminogen activator, which are important for blood clotting and tissue repair. Dysregulation of SERPINE2 has been linked to cardiovascular and neurological disorders, highlighting its importance in maintaining tissue integrity and function.
