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

finProtein required for the switch from F to G during sporulation (anti sigma F); An anti-sigma factor for sporulation specific sigma-F factor, by antagonizing sigma-F it allows the switch to sigma-G factor and progression to the late sporulation development stages. Might stabilize or process Holliday junction intermediates, although this may be due to polar effects on the downstream mfd gene. (76 aa)    
Predicted Functional Partners:
pth
peptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.

csfB
Forespore-specific anti-sigma factor; An anti-sigma-G factor, prevents premature activation of sigma-G factor in the forespore; overexpression leads to 1000-fold reduction in spore formation, spore formation stops after engulfment. Overexpression also inhibits sigma- G transcription activation activity. When both Gin and sigma-G are expressed in E.coli Gin inhibits sigma-G, strongly suggesting Gin inhibits by direct physical interaction.

rsfA
Prespore-specific regulatory gene; Seems to improve the efficiency of sporulation by fine-tuning the expression of genes in the sigma F regulon, particularly the timing of their expression. Negatively regulates spoIIR and its own synthesis.
  
   
 0.832
mfd
Transcription-repair coupling factor; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the N-terminal section; belongs to the UvrB family.
  
    0.807
yabQ
Membrane protein of the forespore; Required for sporulation. Plays an important role in cortex and coat formation.
 
    0.806
gerR
DNA-binding regulator; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
  
  
 0.805
cotE
Morphogenic spore protein; Morphogenic protein required for the assembly of the outer coat of the endospore. Is also a regulatory protein for the expression of cotA, cotB, cotC, cotH and other genes encoding spore outer coat proteins.
  
   
 0.782
spoVID
Morphogenetic spore protein (stage VI sporulation); Required for assembly of a normal spore coat. May be a component of the innermost layer of the spore coat that aids in its adherence to the prespore.
  
   
 0.782
yhbB
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
     0.764
yaaC
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
