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 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

csgDLuxr family transcriptional regulator, csgab operon transcriptional regulatory protein; The master regulator for adhesive curli fimbriae expression; necessary for transcription of the csgBAC/ymdA operon. Plays a positive role in biofilm formation. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription. Low-level constitutive expression confers an adherent curli fimbriae- expressing phenotype, up-regulates 10 genes and down-regulates 14 others (216 aa)    
Predicted Functional Partners:
csgF
Curli production assembly/transport component csgf; May be involved in the biogenesis of curli organelles
 
  
 0.998
csgE
Curli production assembly/transport component csge; May be involved in the biogenesis of curli organelles
 
  
 0.998
csgG
Curli production assembly/transport outer membrane lipoprotein; May be involved in the biogenesis of curli organelles

csgB
Curlin nucleator protein, minor subunit in curli complex; Curlin is the structural subunit of the curli fimbriae. Curli are coiled surface structures that assemble preferentially at growth temperatures below 37 degrees Celsius. Curli can bind to fibronectin. The minor subunit is the nucleation component of curlin monomers. Coexpression of cellulose and thin aggregative fimbriae (curli fimbrae or fibers) leads to a hydrophobic network with tightly packed cells embedded in a highly inert matrix that confers cohesion, elasticity and tissue-like properties to colonies
 
  
 0.972
csgA
Curlin subunit, amyloid curli fibers, cryptic; Curlin is the structural subunit of the curli fimbriae. Curli are coiled surface structures that assemble preferentially at growth temperatures below 37 degrees Celsius. Curli can bind to fibronectin
  
  
 0.959
csgC
Inhibitor of csga amyloid formation; Plays a role in the extracellular assembly of CsgA into thin aggregative fimbriae (Tafi) fibers. Assembly may also require CsgE. Tafi are thought to be assembled via an extracellular nucleation- precipitation (ENP) pathway, and possibly also via an intracellular non-CsgC-dependent pathway (By similarity)

ompR
Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes . 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 Involved in acid stress response; this requires EnvZ but not OmpR phosphorylation . Phosphorylated by EnvZ; this stimulates OmpR's DNA-binding ability Is also dephosphorylated by EnvZ A single OmpR protein can b [...]

mlrA
Merr family transcriptional regulator, activator of the csg genes; Activates transcription of csgD, the master regulator of biofilm formation, by binding to its promoter region Also controls the transcription of cadC and ibaG . Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA

yaiC
Diguanylate cyclase, cellulose regualtor; A probable diguanylate cyclase. The last member of a cascade of expressed proteins, its expression requires DgcM. DgcC production induces biosynthesis of cellulose in some E.coli isolates, but not in K12 strains. Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria

yegE
Putative diguanylate cyclase dgce; Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules (By similarity). Involved in the control of the switch from cell motility to adhesion via regulation of cellular levels of c-di-GMP (Probable). Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di- GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression [...]
