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
Your Input:
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)
phoBRegulates pho regulon (OmpR family); similar to E. coli positive response regulator for pho regulon, sensor is PhoR (or CreC) (AAC73502.1); Blastp hit to AAC73502.1 (229 aa), 95% identity in aa 1 - 229. (229 aa)
phoRSensory 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. (431 aa)
hhaHemolysin expression modulating protein (involved in environmental regulation of virulence factors); Interacts with H-NS and in this complex might contact DNA, which could provide an additional surface for DNA binding to the H-NS- Hha complex; may not bind DNA in the absence of H-NS. In vitro improves the ability of H-NS to bind DNA under a precise set of conditions. (72 aa)
phoQSensory 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 [...] (487 aa)
foxAFerrioxamine receptor; Ferrioxamine binding and uptake, in association with the TonB protein; Belongs to the TonB-dependent receptor family. (702 aa)
sodBIron superoxide dismutase; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems; Belongs to the iron/manganese superoxide dismutase family. (193 aa)
rstASimilar to E. coli response transcriptional regulatory protein (RstB sensor) (AAC74680.1); Blastp hit to AAC74680.1 (242 aa), 84% identity in aa 4 - 242. (243 aa)
ompRResponse regulator in two-component regulatory system with EnvZ; 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). Plays a central role in both acid and osmotic stress responses. Binds to the promoter of both ompC and ompF; at low osmolarity it activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity). (239 aa)
envZSensory 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). (450 aa)
barASensory histidine kinase; Similar to E. coli sensor-regulator, activates OmpR by phophorylation (AAC75828.1); Blastp hit to AAC75828.1 (918 aa), 90% identity in aa 1 - 918. (918 aa)
invFInvasion protein; Transcriptional regulator required for the expression of several genes encoding type III secretion system SPI1 effector proteins. The interaction with SicA is necessary for the activation of sigDE (sopB pipC), sicAsipBCDA, and sopE. (216 aa)
hilDRegulatory helix-turn-helix proteins, araC family; HilD (gi|4455108). (309 aa)
prgHCell invasion protein; Required for invasion of epithelial cells. (392 aa)
hilCaraC family bacterial regulatory helix-turn-helix protein; Positive regulator of the expression of the invasion- associated type III secretion system encoded within SPI-1 (pathogenicity island 1). (295 aa)
recADNA strand exchange and recombination protein; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage. (353 aa)
