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.

kaiB2Putative circadian clock protein. (97 aa)    
Predicted Functional Partners:
kaiC2
Circadian clock protein.
 
 
 
 0.985
kaiC1
Circadian clock protein; Core component of the KaiABC clock protein complex, which constitutes the main circadian regulator in cyanobacteria. Binds to DNA. The KaiABC complex may act as a promoter-nonspecific transcription regulator that represses transcription, possibly by acting on the state of chromosome compaction; Belongs to the KaiC family.
 
 
 
 0.977
kaiA
Circadian clock protein; Component of the kaiABC clock protein complex, which constitutes the main circadian regulator in cyanobacteria. The kaiABC complex may act as a promoter-nonspecific transcription regulator that represses transcription, possibly by acting on the state of chromosome compaction. In the complex, it enhances the phosphorylation status of kaiC. In contrast, the presence of kaiB in the complex decreases the phosphorylation status of kaiC, suggesting that kaiB acts by antagonizing the interaction between kaiA and kaiC. A kaiA dimer is sufficient to enhance kaiC hexamer [...]

cce_4714
Two-component response regulator, NarL subfamily.
 
     0.805
cce_0470
Hypothetical protein; Contains an Anti-sigma factor antagonist domain; Belongs to the anti-sigma-factor antagonist family.
   
  
 0.583
cce_3321
Anti-sigma factor antagonist; Belongs to the anti-sigma-factor antagonist family.
   
  
 0.583
cce_1185
Two-component hybrid sensor and regulator.
   
 
 0.442
rpaB
Two-component response regulator.
      
 0.439
cce_2232
Two-component sensor histidine kinase; Involved in chemotaxis. Part of a chemotaxis signal transduction system that modulates chemotaxis in response to various stimuli. Catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins or MCP) by CheR. Also mediates the irreversible deamidation of specific glutamine residues to glutamic acid. Belongs to the CheB family.
   
 
 0.437
rpl21
50s ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
     
 0.410
