Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) also known as caspase recruitment domain-containing protein 15 (CARD15) or inflammatory bowel disease protein 1 (IBD1) is a protein that in humans is encoded by the NOD2gene located on chromosome 16.[1][2] NOD2 plays an important role in the immune system. It recognizes bacterial molecules (peptidoglycans) and stimulates an immune reaction.
The C-terminal portion of the protein contains a leucine-rich repeat domain that is known to play a role in protein–protein interactions. The middle part of the protein is characterized by a NOD domain involved in protein self-oligomerization. The N-terminal portion contains two CARD domains known to play a role in apoptosis and NF-κB activation pathways.[5]
NOD2 has also been shown to bind to MAVS in response to ssRNA or viral RNA treatment and activate the IFN response. This is the first report of NOD2 acting as a pattern-recognition receptor for viruses.[13]
