Actin-assembly inducing protein precursor; Virulence factor required for host cell microfilament interaction. It induces actin assembly around the bacteria to allow it to move within the cytoplasm. It is involved in the actin polymerization process. It seems to act as a nucleator that induces the reorganization of the actin cytoskeleton.

Flagellin protein; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella.

It is involved in the actin polymerization process. It seems to act as a nucleator that induces the reorganization of the actin cytoskeleton.

Listeriolysin O precursor; Sulfhydryl-activated 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 U [...]

Internalin A; Mediates the entry of L.monocytogenes into host intestinal epithelial cells; transformation with inlA alone allows L.innocua (a non-invasive species) to be taken up by host cells. Binds to human receptor cadherin-1 (E-cadherin, CDH1); the chicken homolog of cadherin-1 but not cadherin- 2 function as receptors. Mouse cadherin-1 is not a receptor, however mutating a single surface-exposed residue (Glu-172 to Pro in mouse) allows cadherin-1 to act as a receptor for InlA ; Belongs to the internalin family.

It is involved in the actin polymerization process. It seems to act as a nucleator that induces the reorganization of the actin cytoskeleton.

Internalin B; Mediates the entry of L.monocytogenes into normally non- phagocytic mammalian host cells. Its host receptor is hepatocyte growth factor receptor (HGF receptor, a tyrosine kinase, MET) which is tyrosine-phosphorylated in response to InlB. Downstream targets MAPK1/MAPK3 (Erk1/2) and AKT are phosphorylated in response to InlB, which also causes cell colony scattering. Complement component 1 Q subcomponent-binding protein (gC1q-R, C1QBP) has been suggested to also act an InlB receptor, but this is less certain. Stimulation of Tyr-phosphorylation of MET by InlB is potentiated [...]
