NALP proteins are cytoplasmic proteins that form a subfamily within the larger CATERPILLER family and are thought to play a crucial role in cell proliferation and reproduction. Like all other NALP family members, NALP11 has a C-terminal leucine-rich repeat (LRR) region, an N-terminal Pyrin domain (PYD) followed by a NACHT domain, and a NACHT-associated domain. While little is known about the function of NALP11, it has been suggested that it has been associated with Crohn's disease.Synonyms: LRR and PYD domains-containing protein 11, NACHT, NLRP11, NOD17, Nucleotide-binding oligomerization domain protein 17, PYPAF6, PYRIN-containing APAF1-like protein 6
