-

Nucleotide-binding oligomerization domain proteins
A family of cytoplasmic proteins that recognize molecules associated with disease-causing bacteria and stimulate cells to secrete cytokines and costimulatory molecules. Inappropriate regulation of nucleotide-binding oligomerization domain proteins has been linked to the pathogenesis of Crohn’s disease and other syndromes.
