Preparation and Storage

Background: NLRP6/NALP6

NLRP6 (Nod-Like Receptor Pyrin domain-containing protein 6), also known as NALP6, PYPAF5 and PAN3, is an 80-85 kDa cytoplasmic member of the NLRP family of proteins. Human NLRP is 892 amino acids (aa) in length, and contains an N-terminal Pyrin domain (aa 1-103), one Nacht region (aa 197-350), and five consecutive C-terminqal leucine-rich repeats (aa 462-868). It is expressed in select cell types, including eosinophils, neutrophils, CD4+ and CD8+ T cells, neurons, myofibroblasts, and intestinal goblet cells plus columnar epithelium. NLRP6 is perhaps best known for its participation in the formation of inflammasomes. Inflammasomes are oligomeric intracellular complexes that serve as detectors for "danger signals" that appear following microbial invasion or unexpected cell death. Following detection, recruited components to the complex (such as Caspase-1) are activated, and subsequently themselves serve to activate pro-IL-1 beta and IL-18. The actual detection of these signals is mediated by the NLRP family, possibly in a tissue specific manner. NLRP6 has been identified in both damaged peripheral nerve and intestinal epithelium. In goblet cells, NLRP6 drives mucus secretion; in intestinal columnar epithelium, NLRP6 acts as a homeostatic agent that promotes epithelial barrier integrity. It accomplishes this by inducing mature IL-18 secretion, a step that then reduces IL-22BP production and leads to an increase in IL-22, a cytokine known for its pro-mucosal homeostatic properties. Although most insults to the intestinal mucosa likely arise from bacteria, NLRP6 is also known to recognize dsRNA-based viruses such as norovirus, and induce the expression of antiviral cytokines such as IFN-alpha, -beta and -lambda. Over aa 35-193, human NLRP6 shares 69% aa sequence identity with mouse NLRP6.
