Human Glia Derived Nexin / GDN (SERPINE2) Protein

Background

SERPINE2, also known as protease nexin-1 (PN-1), is a member of the serpin (serine protease inhibitor) superfamily, which is involved in regulating a wide variety of proteases across different physiological processes. Unlike its closely related counterpart, SERPINE1 (PAI-1), which predominantly regulates fibrinolysis, SERPINE2 plays a more diverse role in modulating tissue remodeling, inflammation, and cellular homeostasis by inhibiting a variety of proteases. These include thrombin, trypsin, urokinase-type plasminogen activator (uPA), and other serine proteases that participate in hemostasis, extracellular matrix degradation, and inflammation. SERPINE2 is expressed in a wide range of tissues, including the brain, lungs, kidneys, and cardiovascular system. Its ability to inhibit multiple serine proteases grants it a broad functional role in physiological processes ranging from coagulation to inflammation.
