Key component of inflammasomes that indirectly senses specific proteins from pathogenic bacteria and fungi and responds by assembling an inflammasome complex that promotes caspase-1 activation, cytokine production and macrophage pyroptosis. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Molecular Function: ATP binding; cysteine protease inhibitor activity; magnesium ion binding; protein binding; protein homodimerization activity; ubiquitin-protein ligase activity
Biological Process: activation of innate immune response; activation of NF-kappaB transcription factor; caspase activation; defense response to bacterium; detection of bacterium; inflammatory response; innate immune response; interleukin-1 beta secretion; positive regulation of apoptosis; protein homooligomerization; regulation of apoptosis; regulation of signal transduction
