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: identical protein binding; protein binding; protein homodimerization activity; magnesium ion binding; ubiquitin-protein ligase activity; cysteine protease inhibitor activity; ATP binding
Biological Process: caspase activation; detection of bacterium; positive regulation of apoptosis; regulation of neuron apoptosis; defense response to bacterium; protein ubiquitination; regulation of signal transduction; innate immune response; interleukin-1 beta secretion; inflammatory response; activation of innate immune response; protein homooligomerization; negative regulation of apoptosis; activation of NF-kappaB transcription factor
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
