== Function ==
'''Crystal Structure of Internalin C from Listeria monocytogenes'''
[https://www.uniprot.org/uniprot/INLC_LISMG INLC_LISMG] A virulence enhancer that has at least 2 dissociable functions in infection; it impairs translocation of host transcription factor NF-kappa-B to the nucleus and antagonizes the function of the Tuba dynamin-binding protein, promoting bacterial spreading (PubMed:20855622, PubMed:19767742, PubMed:24332715). Perturbs the morphology of host cell junctions by impairing host DNMBP (Tuba) and WASL interaction, altering cortical tension at the cell junctions and allowing bacteria to more efficiently form bacteria-filled cell protrusions which promote bacterial spreading within infected host tissue (PubMed:19767742, PubMed:24332715). Down-regulates the host inflammation response usually induced by Listeria infection. Interacts with host I-kappa-B kinase alpha (IKKA, CHUK), which prevents IKKA from phosphorylating NF-kappa-B inhibitor alpha (IKBA, NFKBIA) and thus delays degradation of phospho-IKBA. Translocation of host transcription factor p65 (a subunit of NF-kappa-B, RELA) into the nucleus is impaired, which prevents activation of NF-KB-regulated genes (PubMed:20855622). Recognized by serum from healthy humans exposed to L.monocytogenes as well from patients who have recovered from listeriosis (PubMed:9284184).<ref>PMID:19767742</ref> <ref>PMID:20855622</ref> <ref>PMID:24332715</ref> <ref>PMID:9284184</ref>

==Overview==
Check<jmol>
The crystal structure of internalin C (InlC) from Listeria monocytogenes has been determined at 2.0 A resolution. Several observations implicate InlC in infection: inlC has the same transcriptional activator as other virulence genes, it is only present in pathogenic Listeria strains and an inlC deletion mutant is significantly less virulent. While the extended concave receptor-binding surfaces of the leucine-rich repeat (LRR) domains of internalins A and B have aromatic clusters involved in receptor binding, the corresponding surface of InlC is smaller, flatter and more hydrophilic, suggesting that InlC may be involved in weak or transient associations with receptors; this may help explain why no receptor has yet been discovered for InlC. In contrast, the Ig-like domain, to which the LRR domain is fused, has surface aromatics that may be of functional importance, possibly being involved in binding to the surface of the bacteria or in receptor binding.
