Product Description

Proteinase 3 is one of the serine proteinases localized in azurophil granules of polymorphonuclear leukocytes. It has been identified as the autoantigen of Wegener granulomatosis, a systemic vasculitis complicated by melomonocyte proliferation. It exhibits proteolytic activity towards a range of substrates. It is physiologically inhibited by alpha1-antitrypsin. The protein has been described as having antibiotic and growth-promoting properties and causing emphysema when administered by tracheal insufflation. PRTN3 degrades elastin, fibronectin, laminin, vitronectin, and collagen types I, III, and IV (in vitro) and causes emphysema once managed by tracheal insufflation to hamsters.
