    basic FUNCTION
  • serine proteinase inhibitor of cathepsin G and most cell kinase
  • may act as a protease inhibitor to modulate the host immune response against tumor cells
  • may be involved in the malignant behavior of squamous cell carcinoma cells
  • with SERPINB3, stimulates matrix metalloproteinase-9 production in cervical squamous cell carcinoma cell lines
  • with SERPINB3, are tumor-associated proteins that can inhibit papain-like cysteine proteases, including cathepsins L, K, and S
