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

sigDRNA polymerase sigma-28 factor (sigma-D); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This alternative sigma factor is required for the transcription of the flagellin and motility genes as well as for wild- type chemotaxis. (254 aa)    
Predicted Functional Partners:
flgM
Anti-sigma factor repressor of sigma(D)-dependent transcription; Allows the coupling of early and late flagellar synthesis through the repression of RNA polymerase sigma-D factor-dependent transcription.
 
 0.998
flgB
Flagellar component of cell-proximal portion of basal-body rod; Structural component of flagellum, the bacterial motility apparatus. Part of the rod structure of flagellar basal body.
 
 
 0.993
fliM
Flagellar motor switching and energizing component; One of the proteins that forms a switch complex that is proposed to be located at the base of the basal body. This complex interacts with chemotaxis proteins (such as CheY) in addition to contacting components of the motor that determine the direction of flagellar rotation; Belongs to the FliM family.
 
 
 0.989
hag
Flagellin protein; Flagellin is the subunit which polymerizes to form the filaments of bacterial flagella. Assembly into flagella requires FliW. Acts as a homeostatic autoinhibitory regulator to control its own cytoplasmic levels. Partner switching by flagellin between FliW and CsrA provides a flagellar assembly checkpoint to tightly control the timing of flagellin synthesis. Flagellin binds to assembly factor FliW, freeing translation regulator CsrA to repress translation of the flagellin mRNA. When the flagellar hook is assembled flagellin is secreted, depleting intracellular flagell [...]

flhA
Component of the flagellar export machinery; Involved in the export of flagellum proteins.
 
  
 0.985
flgE
Flagellar hook protein; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type f: factor; Belongs to the flagella basal body rod proteins family.
 
  
 0.982
fliG
Flagellar motor switching and energizing component; One of the proteins that forms a switch complex that is proposed to be located at the base of the basal body. This complex interacts with chemotaxis proteins (such as CheY) in addition to contacting components of the motor that determine the direction of flagellar rotation; Belongs to the FliG family.
 
  
 0.980
fliY
Flagellar motor switching and energizing phosphatase; Component of the flagellar switch. Binds CheY-P and increases its hydrolysis rate in vitro. May function constitutively to remove CheY-P around the flagellar switch to maintain an optimal level of CheY-P whereas CheC may function after addition of an attractant to cope with increased levels of CheY-P; Belongs to the FliN/MopA/SpaO family.
 
  
 0.980
fliQ
Component of the flagellar export machinery; Role in flagellar biosynthesis; Belongs to the FliQ/MopD/SpaQ family.
 
  
 0.979
fliF
Flagellar basal-body M-ring protein; The M ring may be actively involved in energy transduction.
 
  
 0.978
