MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of the serpin family of proteinase inhibitors. Members of this family maintain homeostasis by neutralizing overexpressed proteinase activity through their function as suicide substrates. This protein inhibits the neutrophil-derived proteinases neutrophil elastase, cathepsin G, and proteinase-3 and thus protects tissues from damage at inflammatory sites. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]
PHENOTYPE: Homozygous null mice fail to clear P. aeruginosa lung infection and show increased mortality associated with late-onset failed bacterial clearance, partly due to elevated neutrophil necrosis, release of neutrophil protease activity, higher cytokine production and proteolysis of surfactant protein-D.
