[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 ==
 +
Nod-like receptors (NLRs), Nod1 and Nod2 are cytosolic detectors of pathogen-associated molecular patterns (PAMPs). Nod1 is a three-domain protein, consisting of a caspase activation and recruitment domain (CARD), a nucleotide-binding oligomerization domain (NOD), and a leucine-rich repeat domain (LRR). The binding of PAMPs to the LRR results in the activation of signaling through homophilic CARD-CARD interactions. Several CARD structures have been determined, including a recent NMR structure of Nod1 CARD. In contrast to the reported NMR structure, the crystal structure reported here is a dimer, where the sixth helix is swapped between two monomers. While the overall structure is very similar to the known CARD structures, this is the first report of a homodimeric CARD structure. The ability of the CARD to exist in monomeric and dimeric forms suggests another level of regulation in the activation of NLR proteins.
