Function

[Q8Y9T5_LISMO] Relieves the repression of host cell immune response genes (interferon-stimulated genes) by blocking the recruitment of host BAHD1 to these genes. May modulate interferon-mediated immune response to control bacterial colonization of the host.^[1]

Publication Abstract from PubMed

Intracellular pathogens such as Listeria monocytogenes subvert cellular functions through the interaction of bacterial effectors with host components. Here, we found that a secreted listerial virulence factor, LntA, could target the chromatin repressor BAHD1 in the host cell nucleus to activate interferon (IFN)-stimulated genes (ISGs). IFN-lambda expression was induced in response to infection of epithelial cells with bacteria lacking LntA; however, the BAHD1-chromatin associated complex repressed downstream ISGs. In contrast, in cells infected with lntA-expressing bacteria, LntA prevented BAHD1 recruitment to ISGs and stimulated their expression. Murine listeriosis decreased in BAHD1(+/- )mice or when lntA was constitutively expressed. Thus, the LntA-BAHD1 interplay may modulate IFN-lambda-mediated immune response to control bacterial colonization of the host.
