background:
NALPs are cytoplasmic proteins that form a subfamily within the larger CATERPILLER protein family. Most short NALPs, such as NALP4, have an N-terminal pyrin (MEFV; MIM 608107) domain (PYD), followed by a NACHT domain, a NACHT-associated domain (NAD), and a SLCterminal leucine-rich repeat (LRR) region. The long NALP, NALP1 (MIM 606636), also has a SLCterminal extension containing a function to find domain (FIIND) and a caspase recruitment domain (CARD). NALPs are implicated in the activation of proinflammatory caspases (e.g., CASP1; MIM 147678) via their involvement in multiprotein complexes called inflammasomes (Tschopp et al., 2003 [PubMed 12563287]).[supplied by OMIM, Mar 2008].
Function:
May be involved in inflammation. Acts as a negative regulator of the type I interferon signaling pathway by serving as an adapter to promote DTX4-mediated ubiquitination of activated TBK1, and its subsequent degradation.
Similarity:
Belongs to the NLRP family.
Contains 1 DAPIN domain.
Contains 8 LRR (leucine-rich) repeats.
Contains 1 NACHT domain.
