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

nhaKNa+/H+ antiporter; Transporter involved in the efflux of sodium, potassium, lithium and rubidium. (670 aa)    
Predicted Functional Partners:
yugO
Putative potassium channel protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter.
     
 0.863
nhaC
Na+/H+ antiporter; Is a secondary, electrogenic Na(+)/H(+) antiporter that catalyzes Na(+) uptake and proton efflux. Makes modest contributions to pH homeostasis in the alkaline range of pH but is not contributor to Na(+) resistance. Appears to have a repressive effect on growth and on alkaline phosphatases production in the presence of sodium, by affecting the transcription of the phoP/phoR two-component regulatory system.
      
 0.853
ydaO
Putative metabolite transporter; High-affinity potassium transporter.
  
 
 
 0.831
salA
Mrp family regulator; Binds and transfers iron-sulfur (Fe-S) clusters to target apoproteins. Can hydrolyze ATP; Belongs to the Mrp/NBP35 ATP-binding proteins family.
   
  
 0.774
ktrC
Potassium uptake protein; Catalytic subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.
     
 0.774
yocR
Putative sodium-dependent transporter; Putative sodium-dependent transporter; Belongs to the sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family.
   
  
 0.712
yocS
Putative sodium-dependent transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
      
 0.704
ktrB
Potassium transporter ATPase; Integral membrane subunit of the KtrAB potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.
   
 
 0.693
mrpA
Sodium transporter component of a Na+/H+ antiporter; Mrp complex is a Na(+)/H(+) antiporter that is considered to be the major Na(+) excretion system in B.subtilis. Has a major role in Na(+) resistance and a minor role in Na(+)- and K(+)-dependent pH homeostasis as compared to TetB. MrpA may be the actual Na(+)/H(+) antiporter, although the six other Mrp proteins are all required for Na(+)/H(+) antiport activity and Na(+) resistance. MrpA is required for initiation of sporulation when external Na(+) concentration increases. Also transports Li(+) but not K(+), Ca(2+) or Mg(2+). Belongs [...]
  
  
 0.625
opuD
Glycine betaine transporter; High-affinity uptake of glycine betaine. Does not mediate either carnitine or choline uptake; Belongs to the BCCT transporter (TC 2.A.15) family.
