The NLRP6 protein is very faintly expressed in several normal and cancerous epithelial cells and may be confused with an unrelated protein
Nod-Like Receptor Pyrin domain-containing protein 6 (NLRP6), a member of the Nucleotide-oligomerization domain-Like Receptor (NLR) family of proteins, assembles together with the ASC protein to form an inflammasome upon stimulation by bacterial lipoteichoic acid and double-stranded DNA. Besides its...

description | Nod-Like Receptor Pyrin domain-containing protein 6 (NLRP6), a member of the Nucleotide-oligomerization domain-Like Receptor (NLR) family of proteins, assembles together with the ASC protein to form an inflammasome upon stimulation by bacterial lipoteichoic acid and double-stranded DNA. Besides its expression in myeloid cells, NLRP6 is also expressed in intestinal epithelial cells where it may contribute to the maintenance of gut homeostasis and negatively controls colorectal tumorigenesis. Here, we report that NLRP6 is very faintly expressed in several colon cancer cell lines, detected only in cytoplasmic small dots were it colocalizes with ASC. Consequently, it is very hardly detected by standard western-blotting techniques by several presently available commercial antibodies which, in contrast, highly cross-react with a protein of 90kDa that we demonstrate to be unrelated to NLRP6. We report here these results to caution the community not to confuse the 90kDa protein with the endogenous human NLRP6. |
