MGI Phenotype FUNCTION: The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1. The encoded protein plays a role in thymocyte proliferation and is involved in the inflammatory response. [provided by RefSeq, Aug 2015]
PHENOTYPE: Homozygous null mutants show impaired contact hypersensitivity and reduced acute-phase inflammatory response. Lung tumors and metastases of B16 melanoma do not occur in null mutant mice, suggesting inability to support tumor invasiveness and angiogenesis. [provided by MGI curators]
