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).[1][2][3][4]
