This domain is frequently found associated with the NACHT domain () in fish and other vertebrates []. Proteins containing this domain include NACHT, LRR and PYD domains-containing protein 3/12 (NLRP3/12). In humans, NLRP3 (also known as PYPAF1) may function as an inducer of apoptosis []. NLRP12 is a non-inflammasome NLR (nucleotide-binding domain and leucine-rich repeat-containing receptors) that has been implicated in the regulation of Toll-like receptor-dependent nuclear factor-kappaB activation [].
