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.

phoPResponse regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ which regulates the expression of genes involved in virulence, adaptation to acidic and low Mg(2+) environments and resistance to host defense antimicrobial peptides. Essential for intramacrophage survival of S.typhimurium. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repressio [...] (224 aa)    
Predicted Functional Partners:
phoQ
Sensory kinase protein in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ which regulates the expression of genes involved in virulence, adaptation to acidic and low Mg(2+) environments and resistance to host defense antimicrobial peptides. Essential for intramacrophage survival of S.typhimurium. In low periplasmic Mg(2+), PhoQ functions as a membrane- associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of [...]

basS
Sensory kinase in two-component regulatory system with BasR; Member of the two-component regulatory system BasS/BasR. Autophosphorylates and activates BasR by phosphorylation. Plays a role in the adaptation of the organism to the host environment, in particular to neutrophils, and therefore it plays a role in virulence as well.
 
 0.989
ssrA
Secretion system regulator: Sensor component; SpiR (gi|1498305).
 
 
 0.977
phoR
Sensory kinase in two-component regulatory system with PhoB, regulates pho regulon; Similar to E. coli positive and negative sensor protein for pho regulon (AAC73503.1); Blastp hit to AAC73503.1 (431 aa), 90% identity in aa 1 - 431.
 
 0.968
envZ
Sensory histidine kinase in two-component regulatory system with OmpR; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes (By similarity). EnvZ functions as a membrane- associated protein kinase that phosphorylates OmpR in response to environmental signals; at low osmolarity OmpR activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity).
 
 
 0.964
mgtC
Mg2+ transport protein; Virulence factor required for growth in low Mg(2+) medium and for intramacrophage survival. May be involved in regulating membrane potential by activating Na(+)/K(+)-ATPase. Belongs to the MgtC/SapB family.
   
 
 0.955
yobG
Putative inner membrane protein; PhoP-regulated transcription is redox-sensitive, being activated when the periplasm becomes more reducing. MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway. Represses PhoP/PhoQ signaling, possibly by binding to the periplasmic domain of PhoQ, altering its activity and that of downstream effector PhoP.
   
  
 0.952
pmrD
Polymyxin resistance protein B; Interacts with phosphorylated BasR protein to mediate transcriptional induction of BasR-activated genes to induce polymyxin resistance; Belongs to the PmrD family.
   
  
 0.948
cpxA
Sensory kinase in two-component regulatory system with CpxR; Senses misfolded proteins in bacterial envelope; similar to E. coli probable sensor protein (histidine protein kinase), acting on arcA (AAC76893.1); Blastp hit to AAC76893.1 (457 aa), 96% identity in aa 1 - 457.
 
 
 0.942
rpoS
Sigma S (sigma 38) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response.
