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

flgMAnti-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. (88 aa)    
Predicted Functional Partners:
flgK
Flagellar hook-filament junction; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; structure.
 
  
 0.999
yvyG
Putative flagellar protein; May be involved in the assembly, structure, or function of the flagellum. May polymerize to form a filamentous structure that is part of the flagellum.
 
  
 0.999
sigD
RNA 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.
 
 0.998
fliS
Flagellar assembly protein FliS; Essential for filament assembly. May act as a facilitator of flagellin (hag) secretion. Antagonizes translational repressor CsrA indirectly. Belongs to the FliS family.
  
 
 0.997
yvyF
Putative regulator of flagella formation; May be involved in the assembly, structure, or function of the flagellum. May polymerize to form a filamentous structure that is part of the flagellum.
 
 
 0.997
fliD
Flagellar hook-associated capping protein 2 (HAP2); Required for the morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament. Forms a capping structure, which prevents flagellin subunits (transported through the central channel of the flagellum) from leaking out without polymerization at the distal end (By similarity); Belongs to the FliD family.
 
  
 0.996
flgL
Flagellar hook-filament junction; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; structure.
  
  
 0.996
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 [...]
  
  
 0.987
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.
  
  
 0.983
fliJ
Flagellar synthesis chaperone; Flagellar protein that affects chemotactic events.
  
  
 0.978
