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.

spoIIABPutative 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. (157 aa)

Anti-sigma-factor antagonist; TIGRFAM: anti-anti-sigma factor; anti-sigma F factor antagonist; PFAM: Sulfate transporter/antisigma-factor antagonist STAS; KEGG: amt:Amet_2212 anti-sigma-factor antagonist.

Cphy_0478
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.
 
 
 0.993
Cphy_2470
Peptidase U4 sporulation factor SpoIIGA; Probable aspartic protease that is responsible for the proteolytic cleavage of the RNA polymerase sigma E factor (SigE/spoIIGB) to yield the active peptide in the mother cell during sporulation. Responds to a signal from the forespore that is triggered by the extracellular signal protein SpoIIR. Belongs to the peptidase U4 family.

Cphy_2497
Sporulation transcriptional activator Spo0A; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process.
