Cytosolic proteins NODs involved in the regulation of immune and inflammatory responses / 中国病理生理杂志

Nucleotide-binding oligomerization domain (NOD) proteins are members of a growing family of cytosolic factors related to the apoptosis regulator Apaf-1 and a class of plant disease resistance proteins. NOD proteins have been implicated in the induction of NF-?B activity and in the activation of caspases. Biochemical evidence has unraveled the role of NOD1 and NOD2 as intracellular sensors of bacterial peptidoglycan. Notably, genetic variation in the genes encoding the NOD proteins NOD2, cryopyrin and CⅡTA in humans is associated with inflammatory disease or increased susceptibility to bacterial infections. NOD proteins may be involved in the recognition of microorganisms and regulation of inflammatory responses. [
