Product Description

Human Cathepsin G


Human Cathepsin G is a serine protease secreted by activated neutrophils that play a role in the inflammatory response. This enzyme degrades collagen and proteoglycan and can also cause the release of angiotensin II from angiotensin I or angiotensinogen. It has been implicated in connective tissue diseases such as emphysema and rheumatoid arthritis.2 to 4 units per mg protein. One unit of activity is defined as the amount of enzyme that hydrolyzes one micromole of Suc-Ala-Ala-Pro-Phe-pNA (1 mM) per minute at 25C in 160 mM Tris-HCl, pH 7.4, with 1.6 M NaCl.

Cathepsin G has a specificity similar to that of chymotrypsin C, but it is most closely related to other immune serine proteases, such as neutrophil elastase and the granzymes. Cathepsin G has been reported to play an important role in a variety of diseases, including rheumatoid arthritis, coronary artery disease, periodontitis, ischemic reperfusion injury, and bone metastasis. It is also implicated in a variety of infectious inflammatory diseases, including chronic obstructive pulmonary disease, acute respiratory distress syndrome, and cystic fibrosis.

This product is for in vitro research use only, is not to be consumed by animals or humans, and should be handled with general precaution as if capable of spreading infectious disease.
