Secondary Accession Numbers None
Name Staphopain A
Synonyms
  1. Staphylococcal cysteine proteinase A
  2. Staphylopain A
Gene Name SSPP
Protein Type Unknown
Biological Properties
General Function Not Available
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).
