NACHT, LRR and PYD domains-containing protein 9B (Nlrp9b)

As the sensor part of the NLRP9 inflammasome, plays a crucial role in innate immunity and inflammation. In response to pathogens, such as rotavirus, initiates the formation of the inflammasome polymeric complex, made from NLRP9, PYCARD and CASP1.

Recruitment of proCASP1 into the inflammasome promotes its activation and CASP1-catalyzed IL1B and IL18 maturation and release in the extracellular milieu. The active cytokines stimulate inflammatory reactions.
