Functions as key mediator in apoptosis and inflammation (PubMed:12464617).

Promotes caspase-mediated apoptosis (PubMed:12464617).

Induces proteolytic processing of caspa and caspa-dependent apoptosis (PubMed:12464617).

In innate immune response acts as an integral adapter in the assembly of NLRP1 inflammasomes which activate caspases caspa and caspb leading to processing and secretion of the proinflammatory cytokine il1b (PubMed:30150286).

The function as activating adapter in different types of inflammasomes is mediated by the pyrin and CARD domains and their homotypic interactions (PubMed:30150286).

Also involved in transcriptional activation of cytokines and chemokines independent of the inflammasome.

Self-associates (via pyrin and CARD domains) (PubMed:12464617, PubMed:29791979).

Interacts (via pyrin domain) with caspa (via pyrin domain) (PubMed:12464617, PubMed:30150286, PubMed:29791979).

Interacts with caspb; the interaction only occurs in the presence of nlrp1 (PubMed:30150286).

Component of NLRP1 inflammasomes (PubMed:30150286). Inflammasomes are supramolecular complexes that assemble in the cytosol in response to pathogens and other damage-associated signals and play critical roles in innate immunity and inflammation (PubMed:30150286). The NLRP1 inflammasome is composed of the signal sensor nlrp1, and the adapter pycard (asc), which recruit effector proinflammatory caspases caspa and/or caspb (PubMed:30150286). The interaction between nlrp1 and pycard is required for the sequential recruitment of caspa and then caspb (PubMed:30150286). Within the complex caspa is preferentially recruited first and this causes the cleavage of pro-il1b into the midformed il1b (PubMed:30150286). This is followed by the recruitment of caspb, which is activated and cleaves the midformed il1b resulting in il1b maturation (PubMed:30150286).

Interacts (via pyrin domain) with NLP3X1 (via pyrin domain) (PubMed:29791979).
