	intracellular,cytoplasm

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
