NOD2 is a symbol for the gene, Nucleotide binding oligomerization domain containing 2, in humans. Other names include: Nucleotide-binding oligomerization domain-containing protein 2; Caspase recruitment domain-containing protein 15; Inflammatory bowel disease protein 1; nucleotide-binding oligomerization domain, leucine rich repeat and CARD domain containing 2; NOD-like receptor C2; NLR family, CARD domain containing 2; ACUG; BLAU; CARD15; CLR16.3; NLRC2; NOD2B; PSORAS1; nucleotide-binding oligomerization domain containing 2. The encoded protein has an amino acid length of 1040 and a mass of 115.3 kDa. Other isoforms may exist. This gene shares homology with other species, including: Mouse, Rat, Zebrafish.
