Target Background

Function
A cholesterol-dependent pore-forming toxin, which is a major virulence factor required for the escape of bacteria from phagosomal vacuoles and entry into the host cytosol. After binding to target membranes, the protein undergoes a major conformation change, leading to its insertion in the host membrane and formation of an oligomeric pore complex. Listeriolysin O activates mitogen-activated protein (MAP) kinase activity in host cells, most likely as a result of the permeabilization of the host cell membrane. Also induces a proteasome-independent degradation of UBE2I (the SUMO-conjugating enzyme UBC9) and a proteasome-dependent degradation of some sumoylated proteins. Finally, is necessary and sufficient for spacious Listeria-containing phagosomes (SLAPs) formation, suggesting a role for listeriolysin O in promoting L.monocytogenes replication in vacuoles, leading to persistent infection. Recognized by serum from healthy humans exposed to L.monocytogenes as well from patients who have recovered from listeriosis.
Gene References into Functions
  1. Listeriolysin O -induced down-regulation of Ubc9 is independent of Ubc9-SUMO interaction, however, it may involve phosphorylation signaling. PMID: 28911869
  2. During infection, PML undergoes oxidation-mediated multimerization, associates with the nuclear matrix, and becomes de-SUMOylated due to the pore-forming activity of the Listeria toxin listeriolysin O (LLO). PMID: 28074026
  3. The current MD simulation work provides insights into the mechanism by which the compounds inhibit LLO at the atomic level and will be useful for the development of new, selective LLO inhibitors. PMID: 25749652
  4. Listeria L. monocytogenes induced decrease in hTERT levels is triggered by listeriolysin O (LLO). PMID: 23006849
  5. findings show that listeriolysin O and other cholesterol-dependent cytolysins induce K+ efflux through pore formation at the cell membrane PMID: 21482680
  6. Data suggest that CFTR transiently increases phagosomal chloride concentration after infection, potentiating LLO pore formation and vacuole lysis. PMID: 21220348
  7. These data showed that listeriolysin O-mediated cytoplasmic entry of Listeria monocytogenes could induce the activation of intracellular calcium signaling, which is essential for maturation and secretion of IL-1 alpha in macrophages. PMID: 20194588
  8. L. monocytogenes-infected human PBMCs produced IL-1beta, largely depending on an LLO-mediated phagosomal rupture and cathepsin B release, which is sensed by Nlrp3 PMID: 20008285
  9. These results reveal the importance of the 91-99 region in the production of a stable and functional LLO. LD(50) determinations in the mouse model suggest a possible link between LLO stability and virulence. PMID: 16622046
  10. Listeria monocytogenes-induced caspase-1 activation and interferon-gamma production in mouse macrophages is ascribed mainly to the presence of listeriolysin O. PMID: 18523249
