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

TB31.7Universal stress protein family protein TB31.7; May play a role in the establishment of a persistent infection (latency) in the host, as strains without this gene are hypervirulent. Overexpression of the protein retards growth in culture; Glu-15 and Ala-117 mutant proteins which bind less ATP do not show this retardation, suggesting growth may be regulated through an ATP- dependent function. (297 aa)    
Predicted Functional Partners:
hspX
Heat shock protein HspX (alpha-crystallin homolog) (14 kDa antigen) (HSP16.3); Acts as a chaperone, as it has a significant ability to suppress the thermal denaturation of alcohol dehydrogenase. Cells overexpressing this gene grow more slowly than wild-type cells, and are less susceptible to autolysis following saturation of the culture in vitro, suggesting this protein may slow down the growth rate of M.tuberculosis in culture and by extension during macrophage infection. Belongs to the small heat shock protein (HSP20) family.

hrp1
Hypoxic response protein 1 Hrp1; Unlike some other CBS-domain containing proteins does not seem to bind AMP.
  
  
 0.949
devR
Two component transcriptional regulatory protein DevR (probably LuxR/UhpA-family); Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. When phosphorylated binds and activates the promoter of DevR regulon genes in response to hypoxia. The presence of target DNA increases stability of phospho-DevR in vitro. Activates its own transcription under hypoxic but not aerobic conditions, probably binds as a dimer to tandem binding sites within the devR and hspX promoters. Accepts [...]

Rv3131
Conserved protein; Stimulates pro-inflammatory cytokine expression via TLR2 signaling pathway. Activation of TLR2 results in the phosphorylation and activation of NF-kappa-B. Also induces TLR2 expression. May influence the innate immune responses to facilitate the survival of M.tuberculosis in the granulomatous microenvironment. Belongs to the nitroreductase family.
