Baculoviral IAP repeat-containing protein 1e (Naip5)

Sensor part of the NLRC4 inflammasome that specifically recognizes and binds flagellin from pathogenic bacteria such as Legionella or Salmonella (PubMed:12526741, PubMed:21874021, PubMed:21918512, PubMed:29146805, PubMed:29182158). Association of pathogenic bacteria proteins drives in turn drive assembly and activation of the NLRC4 inflammasome, promoting caspase-1 activation, cytokine production and macrophage pyroptosis (PubMed:21874021, PubMed:21918512, PubMed:29146805, PubMed:29182158).

The NLRC4 inflammasome is triggered as part of the innate immune response to a range of intracellular bacteria. The NLRC4 inflammasome senses Gram- negative bacteria such as L.
