Technical Data
NOD2 (Nucleotide Binding Oligomerization Domain 2, NOD2 Protein, NOD2B, Arthrocutaneouveal Granulomatosis, ACUG, BLAU, Caspase Recruitment Domain 15, CARD15, CD, Inflammatory Bowel Disease Protein 1, IBD1, LRR Containing Protein, PSORAS1)
Innate immunity is present in all animals and is the common mode of defense against microorganisms. It detects microorganisms by specific proteins called pattern-recognition molecules (PRMs). There is a limited set of PRMs in each animal genome, and it has been postulated that the PRMs were evolutionarily selected to detect conserved components or motifs of microorganisms called pathogen-associated molecular patterns (PAMPs). PAMPs are found in a wide range of microorganisms and recognition of PAMPs by PRMs activates inflammatory signaling pathways, thereby stimulating an immune response. NOD (nucleotide-binding oligomerization domain) proteins are a family of cytosolic proteins which have been implicated in innate recognition of bacteria, the induction of inflammatory responses, and the regulation of caspase activation and apoptosis. NOD2:CARD15 (caspase-recruitment domain 15) is a PRM that recognizes specific peptidoglycan (PGN) components of bacterial cell walls. NOD2 is expressed in cells that are exposed to PGN under physiological conditions including antigen-presenting cells (APCs) such as macrophages and dendritic cells, and epithelial cells. NOD2 is a for thought to play a role in the pathogenesis of human gastrointestinal disease. Polymorphisms and mutations in NOD2 are associated with susceptibility to Crohn's disease, a chronic inflammatory bowel disease. Additionally, polymorphisms in NOD2 have also been found to be associated with Graft-versus-Host Disease (GVHD). This association of NOD2 gene polymorphisms with gastrointestinal disease and GVHD suggests that NOD2 gene polymorphisms play a role in pro-inflammatory diseases. NOD2 is a 1040aa protein.
