+== Function ==
+[https://www.uniprot.org/uniprot/NOD1_HUMAN NOD1_HUMAN] Enhances caspase-9-mediated apoptosis. Induces NF-kappa-B activity via RIPK2 and IKK-gamma. Confers responsiveness to intracellular bacterial lipopolysaccharides (LPS). Forms an intracellular sensing system along with ARHGEF2 for the detection of microbial effectors during cell invasion by pathogens. Required for RHOA and RIPK2 dependent NF-kappa-B signaling pathway activation upon S.flexneri cell invasion. Involved not only in sensing peptidoglycan (PGN)-derived muropeptides but also in the activation of NF-kappa-B by Shigella effector proteins IpgB2 and OspB. Recruits NLRP10 to the cell membrane following bacterial infection.<ref>PMID:11058605</ref> <ref>PMID:19043560</ref> <ref>PMID:22672233</ref> <ref>PMID:17054981</ref>

+== Publication Abstract from PubMed ==
+Nod1 is an essential cytoplasmic sensor for bacterial peptidoglycans in the innate immune system. The caspase-recruitment domain of Nod1 (Nod1_CARD) is indispensable for recruiting a downstream kinase, receptor-interacting protein 2 (RIP2), that activates nuclear factor-kappaB (NF-kappaB). The crystal structure of human Nod1_CARD at 1.9 A resolution reveals a novel homodimeric conformation. Our structural and biochemical analysis shows that the homodimerization of Nod1_CARD is achieved by swapping the H6 helices at the carboxy termini and stabilized by forming an interchain disulfide bond between the Cys39 residues of the two monomers in solution and in the crystal. In addition, we present experimental evidence for a pH-sensitive conformational change of Nod1_CARD. Our results suggest that the pH-sensitive monomer/dimer transition is a unique molecular property of Nod1_CARD.
