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

hlyAHaemolysin; Bacterial hemolysin that causes cytolysis by forming heptameric pores in target host membranes. (741 aa)    
Predicted Functional Partners:
hlyB
Hemolysin secretion protein HylB; Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation.

rtxA
RTX toxin RtxA; [Multifunctional-autoprocessing repeats-in-toxin]: Precursor of a multifunctional toxin that causes destruction of the actin cytoskeleton by covalent cross-linking of actin and inactivation of Rho GTPases when translocated into the host cytoplasm. Upon translocation into the host cell, undergoes autoprocessing in cis mediated by the peptidase C80 domain (also named CPD domain): the protease activity is activated upon binding inositol hexakisphosphate (InsP6) present at the host cell membrane and delivers the Cysteine protease domain-containing toxin F3 chain to the host [...]

tcpA
Toxin co-regulated pilin; Constituent of pili, which may be involved in adhesion of V.cholerae to the host intestinal epithelium.
      
 0.546
ctxA
Cholera enterotoxin, A subunit; The A1 chain catalyzes the ADP-ribosylation of Gs alpha, a GTP-binding regulatory protein, to activate the adenylate cyclase. This leads to an overproduction of cAMP and eventually to a hypersecretion of chloride and bicarbonate followed by water, resulting in the characteristic cholera stool. The A2 chain tethers A1 to the pentameric ring.
      
 0.546
toxR
Cholera toxin transcriptional activator; This transcription activator controls cholera toxin, pilus colonization factor and outer membrane protein expression in V.cholerae. It binds to the 5'-TTTTGAT-3' tandemly repeated DNA sequence in the cholera toxin promoter region. ToxS interacts with the C-terminal periplasmic domain of ToxR, stimulating its activity. It activates transcription at the promoters for tcpI and tcpA and this is presumably via ToxT.
      
 0.545
tolC
Outer membrane protein TolC; Outer membrane channel, which is required for the function of several efflux systems (By similarity). Required to export RtxA cytotoxin; Belongs to the outer membrane factor (OMF) (TC 1.B.17) family.
      
 0.534
ompU
Outer membrane protein OmpU; Forms pores that allow passive diffusion of small molecules across the outer membrane.
      
 0.517
zot
Zona occludens toxin; Increases the permeability of the small intestine mucosa by affecting the structure of intercellular tight junctions (zonula occludens).
      
 0.509
hlyC
Lactonizing lipase; Catalyzes the hydrolysis of triacylglycerol. Belongs to the AB hydrolase superfamily. Pseudomonas lipase family.
  
  
 0.507
rtxC
RTX toxin activating protein; Involved in fatty acylation of the protoxin (RtxA) at two internal lysine residues, thereby converting it to the active toxin. The acyl donor is ACP (By similarity).
