SERPINB1 is a member of the serpin family and Ov-serpin subfamily. As protease inhibitors; serpins have an array of functions including regulating blood coagulation; fibrinolysis; the complement pathway; angiogenesis; inflammation; tumor suppression; extracellular matrix remodeling; and cell motility. SERPINB1 regulates the activity of the neutrophil proteases elastase; cathepsin G; proteinase-3; chymase; chymotrypsin; and kallikrein-3. Reactive bond 1 of SerpinB1 is specific for reaction with chymotrypsin-like protease such as cathepsin G; chymotrypsin or chymase. Reactive bond 2 of SerpinB1 is specific for reaction with elastase-like protease such as neutrophyl elastase; proteinase-3; pancreatic elastase or PSA. In addition; SERPINB1 also functions as a potent intracellular inhibitor of granzyme H.
Recombinant Human Serine Protease Inhibitor-clade B1 is produced by our Mammalian expression system and the target gene encoding Met1-Pro379 is expressed with a 6His tag at the C-terminus.
