Description

NLRP11 (NLR family pyrin domain containing 11) is a member of the nucleotide-binding and leucine-rich repeat (NLR) family. It functions as a pattern recognition receptor (PRR) in the innate immune system, involved in the formation of inflammasomes and activation of inflammatory signaling pathways, including NF-κB and caspase-1. NLRP11 is primarily expressed in immune tissues and plays a role in host defense against pathogens.

Mutations & Variants

Hotspot Mutations
Variant Type Frequency Functional Description
c.1003C>T (p.Arg335Trp) Missense 0.001% (gnomAD) Altered ATP-binding and reduced inflammasome activity
c.1546G>A (p.Gly516Arg) Missense 0.0005% (gnomAD) Impaired oligomerization and IL-1β secretion
c.2110delC (p.Leu704Trpfs*12) Frameshift <0.0001% Loss of function; truncated protein
Mutation functional classification

Loss of Function (LOF)

Frameshift and nonsense mutations (e.g., c.2110delC) lead to truncated protein and loss of inflammasome activity.

Gain of Function (GOF)

Not well characterized; some missense variants may enhance NF-κB signaling.

Dominant Negative (DN)

Missense variants in the NACHT domain (e.g., p.Arg335Trp) may interfere with wild-type NLRP11 function.

Gene Ontology (GO)

• ATP binding • protein homodimerization activity
• cysteine-type endopeptidase activator activity involved in apoptotic process • inflammasome complex
• innate immune response • positive regulation of NF-κB transcription factor activity
• positive regulation of interleukin-1 beta production

Pathways

• NOD-like receptor signaling pathway (KEGG: hsa04621)
• Inflammasome pathway (Reactome: R-HSA-844456)

Protein Summary

NLRP11 is a 1,033-amino-acid protein containing an N-terminal pyrin domain (PYD), a central NACHT domain, and C-terminal leucine-rich repeats (LRRs). It acts as a scaffold for inflammasome assembly, recruiting ASC and pro-caspase-1 via PYD-PYD interactions. Upon activation by microbial ligands or cellular stress, NLRP11 promotes caspase-1 cleavage and IL-1β/IL-18 maturation. Its expression is restricted to immune cells and tissues, and it is implicated in autoimmune and infectious diseases.
