Cysteine protease that plays an important role in the inhibition of host innate immune response. Cleaves host elastins found in connective tissues, pulmonary surfactant protein A in the lungs, and the chemokine receptor CXCR2 on leukocytes. Proteolytic cleavage of surfactant protein A impairs bacterial phagocytocis by neutrophils while CXCR2 degradation blocks neutrophil activation and chemotaxis. Additionally, promotes vascular leakage by activating the plasma kallikerin/kinin system, resulting in hypotension. Source: Recombinant protein corresponding to aa215-388 from Staphylococcus aureus Staphopain A, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E.coli.
