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:
fimZFimbrial protein Z; Putative transcriptional regulator (LuxR/UhpA family); fimbriae Z protein. (SW:FIMZ_SALTY). (210 aa)
dnaKChaperone Hsp70; Acts as a chaperone. (638 aa)
araCTranscriptional regulator (AraC/XylS family) for ara operon; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. (281 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)
cydASimilar to E. coli cytochrome d terminal oxidase, polypeptide subunit I (AAC73827.1); Blastp hit to AAC73827.1 (523 aa), 96% identity in aa 2 - 523. (522 aa)
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)
fliZPutative regulator of FliA; May regulate sigma factor activity. (183 aa)
STM2730Fels-2 prophage protein; Similar to retron in E coli; similar to E. coli DNA adenine methylase (AAC76412.1); Blastp hit to AAC76412.1 (278 aa), 46% identity in aa 8 - 266. (285 aa)
csrACarbon storage regulator; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s). (61 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)
prgHCell invasion protein; Required for invasion of epithelial cells. (392 aa)
hilDRegulatory helix-turn-helix proteins, araC family; HilD (gi|4455108). (309 aa)
iagBInvasion protein IAGB precursor. (SW:IAGB_SALTY); Belongs to the IagB/IpgF/P19 family. (160 aa)
sipBCell invasion protein; Required for entry into the host cell through presentation or delivery of SipC at the host cell plasma membrane. Along with SipC, is necessary for the transfer of other effector proteins into the host cell. Induces macrophage apoptosis either by binding and activating the proapoptotic enzyme caspase-1 (caspase-1 dependent), resulting in the release of interleukin-1 beta active form, or by disrupting mitochondria and inducing autophagy (caspase-1 independent). The former is dependent of its membrane-fusion activity. The SipBC complex, in association with its chape [...] (593 aa)
sicASurface presentation of antigens; Type III secretion-associated chaperone required for SipB and SipC stabilization. Prevents premature association of SipB with SipC, which may lead to their targeting for degradation. Along with InvF, required for transcription activation of sigDE (sopB pipC), sicAsipBCDA, and sopE. (165 aa)
spaOSurface presentation of antigens; Involved in a secretory pathway responsible for the surface presentation of determinants needed for the entry of Salmonella species into mammalian cells. (303 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)
invHInvasion protein; Involved in the synthesis of the type III secretion system (T3SS), also called injectisome, which is used to inject bacterial effector proteins into eukaryotic host cells. Pilot protein that is required for the proper localization of the secretin InvG/SctC in the outer membrane. Required for the secretion of the Sip virulence factors. (147 aa)
damDNA adenine methylase; Methylates DNA within the sequence GATC and protects the DNA from cleavage by the restriction endonuclease MboI. Although it shares sequence specificity with a number of type II restriction endonucleases and methylases, it is thought to act in postreplication mismatch repair rather than as a part of a restriction modification system. May also play a role in DNA replication; Belongs to the N(4)/N(6)-methyltransferase family. (278 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)
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)
cpxASensory 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. (457 aa)
