Function
MALE_ECOLI Involved in the high-affinity maltose membrane transport system MalEFGK. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.ASC_DANRE Functions as key mediator in apoptosis and inflammation (PubMed:12464617, PubMed:30150286). Promotes caspase-mediated apoptosis (PubMed:12464617). Induces proteolytic processing of caspa and caspa-dependent apoptosis (PubMed:12464617). Involved in innate immune response by acting as an integral adapter in the assembly of various inflammasomes which recruit and activate caspase-1 leading to processing and secretion of pro-inflammatory cytokines (PubMed:30150286). Caspase-1-dependent inflammation leads to macrophage pyroptosis, a form of cell death (By similarity). The function as activating adapter in different types of inflammasomes is mediated by the pyrin and CARD domains and their homotypic interactions (PubMed:30150286). Clustered PYCARD nucleates the formation of caspase-1 filaments through the interaction of their respective CARD domains, acting as a platform for of caspase-1 polymerization (By similarity). Also involved in transcriptional activation of cytokines and chemokines independent of the inflammasome (By similarity).[UniProtKB:Q9ULZ3][1] [2]
