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

Csac_1657Anti-sigma-factor antagonist; TIGRFAM: anti-anti-sigma factor; PFAM: Sulfate transporter/antisigma-factor antagonist STAS; Belongs to the anti-sigma-factor antagonist family. (109 aa)    
Predicted Functional Partners:
spoIIAB
Putative anti-sigma regulatory factor, serine/threonine protein kinase; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
 
 
 0.980
Csac_1270
CheC, inhibitor of MCP methylation; TIGRFAM: flagellar motor switch protein FliN; PFAM: surface presentation of antigens (SPOA) protein; CheC domain protein.
  
   0.886
Csac_0459
Putative anti-sigma regulatory factor, serine/threonine protein kinase.
 
 
 0.878
Csac_1659
RNA polymerase, sigma 28 subunit, FliA/WhiG family; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
