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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

fliARNA polymerase sigma factor FliA; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes (239 aa)    
Predicted Functional Partners:
flgM
Negative regulator of flagellin synthesis; Responsible for the coupling of flagellin expression to flagellar assembly by preventing expression of the flagellin genes when a component of the middle class of proteins is defective. It negatively regulates flagellar genes by inhibiting the activity of FliA by directly binding to FliA
 
 0.999
fliZ
Regulator of sigma S factor FliZ; During the post-exponential growth phase transiently interferes with RpoS (sigma S) activity without affecting expression of RpoS itself. It is probably not an anti-sigma factor as its overexpression is detrimental in rapidly growing cells where there is almost no sigma S factor. There is a strong overlap between Crl-activated genes and FliZ-down-regulated genes. FliZ acts as a timing device for expression of the genes for the adhesive curli fimbriae by indirectly decreasing expression of the curli regulator CsgD
  
 0.999
fliC
Flagellin; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella
  
 0.999
flgC
Flagellar biosynthesis, cell-proximal portion of basal-body rod; Protein involved in flagellum assembly and taxis
 
 
 0.997
flgB
Flagellar basal body rod protein FlgB; Structural component of flagellum, the bacterial motility apparatus. Part of the rod structure of flagellar basal body (By similarity)
 
 
 0.995
fliD
Flagellar hook-associated protein 2; 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; Belongs to the FliD family
 
  
 0.995
fliM
Flagellar motor switch protein FliM; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation
 
  
 0.995
flgK
Flagellar biosynthesis, hook-filament junction protein 1; Protein involved in flagellum assembly, protein folding and taxis; Belongs to the flagella basal body rod proteins family
 
  
 0.992
flgL
Flagellar biosynthesis; hook-filament junction protein; Protein involved in flagellum assembly, protein folding and taxis
 
  
 0.991
flgE
Flagellar biosynthesis, hook protein; Protein involved in flagellum assembly and taxis
 
  
 0.989
