Functioni

Acid-stable proteinase inhibitor with strong affinities for trypsin, chymotrypsin, elastase, and cathepsin G (PubMed:9126337). Modulates the innate immune response after bacterial infection (PubMed:12615907). Contributes to regulate the inflammatory and immune responses to the intracellular parasite L.major (PubMed:25030421). Down-regulates responses to bacterial lipopolysaccharide (LPS) (PubMed:9039268, PubMed:12615907, PubMed:25030421). Plays a role in regulating the activation of NF-kappa-B and inflammatory responses (PubMed:11017147, PubMed:12615907). Has antimicrobial activity against mycobacteria, but not against salmonella (PubMed:18322212). Contributes to normal resistance against infection by M.tuberculosis (PubMed:18322212). Required for normal resistance to L.major (PubMed:25030421). Required for normal wound healing, probably by preventing tissue damage by limiting protease activity (PubMed:11017147, PubMed:25030421). Together with ELANE, required for normal differentiation and proliferation of bone marrow myeloid cells (By similarity).By similarityCurated7 Publications

Disruption phenotypei

Mutant mice show delayed epithelial wound healing and an increased inflammatory response at the site of wounding, possibly due to increased elastase activity (PubMed:11017147, PubMed:25030421). Mutant mice show an increased tendency to die from toxic shock after exposure to bacterial lipopolysaccharide (LPS) (PubMed:12615907). Mutant mice are highly susceptible to M.tuberculosis; all die within 50 days after infection (PubMed:18322212). Mutant mice are highly susceptible infection by L.major. Contrary to what is observed with wild-type, the parasites are not restricted to the initial site of infection, but spread to spleen, liver and bone morrow. The skin lesions at the initial site of infection do not heal normally, but become bigger over time, in parallel with the spread of the parasites. The inflammatory response at the site of infection is more intense and persists longer than normal. Increased protease activity is observed in these lesions and may be the cause of the extensive tissue damage and necrosis (PubMed:25030421).4 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
