STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

prfAListeriolysin positive regulatory protein; Positively regulates expression of listeriolysin, of 1- phosphadidylinositol phosphodiesterase (PI-PLC) and other virulence factors. (237 aa)    
Predicted Functional Partners:
plcA
Phosphatidylinositol-specific phospholipase c; Cleaves glycosylphosphatidylinositol (GPI) and phosphatidylinositol (PI) anchors but not PI phosphates. Important factor in pathogenesis, PI-PLC activity is present only in virulent listeria species. It may participate in the lysis of the phagolysosomal membrane.

hly
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 [...]

actA
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.
  
  
 0.894
plcB
Phospholipase C; Important role in the infectious process. May contribute to efficient lysis of the two-membrane vacuoles that surround the bacteria after direct cell-to-cell spread.
  
  
 0.888
mpl
Zinc metalloproteinase precursor; Probably linked to the pathogenesis of listerial infection; Belongs to the peptidase M4 family.
  
  
 0.867
lmo1734
Lmo1734 protein; Similar to glutamate synthase (large subunit).
    
 0.858
lmo0206
Uncharacterized protein Lmo0206.
  
  
 0.853
inlB
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 [...]
   
  
 0.851
nifJ
NifJ protein; Highly similar to pyruvate-flavodoxin oxidoreductase.
    
 0.799
lmo1204
Cobalt transport protein CbiM; Part of the energy-coupling factor (ECF) transporter complex CbiMNOQ involved in cobalt import.
