Specific Function
| 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 (PubMed:3422637, PubMed:23235402). Proteolytic cleavage of surfactant protein A impairs bacterial phagocytocis by neutrophils while CXCR2 degradation blocks neutrophil activation and chemotaxis (PubMed:3422637, PubMed:23235402). Additionally, promotes vascular leakage by activating the plasma kallikerin/kinin system, resulting in hypotension (PubMed:15897280). |
