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

sll0689Na/H+ antiporter; Na(+)/H(+) antiporter that transports sodium from the cytoplasm into the thylakoid lumen in exchange for protons. Contributes to sodium homeostasis and tolerance. Has also Li(+)/H(+) antiport activity under K(+)-free conditions, but not under K(+)-rich conditions; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transporter (TC 2.A.37) family. (461 aa)    
Predicted Functional Partners:
slr1727
Eukaryotic Na+/H+ exchanger; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Might be able to function at relatively high concentrations of Na(+) ions. Has also Li(+)/H(+) antiport activity under K(+)-rich conditions, but it might not have any physiological relevance.
   
 
 0.912
sll0273
Na+/H+ exchanger; Required for Na(+) uptake into the cell, especially at low external Na(+) concentrations or low Na(+)/K(+) ratios. May be part of a sodium cycle that permits re-entry of sodium into the cell.
   
 
 0.908
pxcA
PxcA; Involved in light-induced Na(+)-dependent proton extrusion. Also seems to be involved in CO(2) transport; Belongs to the Cema family.
      
 0.892
sll0556
ORF_ID:sll0556; unknown protein; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transporter (TC 2.A.37) family.
   
 
 0.885
slr0822
Cation-transporting ATPase; ORF_ID:slr0822.
  
 
 0.724
slr2131
Cation or drug efflux system protein; ORF_ID:slr2131; Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
     
 0.680
slr1507
ORF_ID:slr1507; unknown protein.
      
 0.676
kdpA
Potassium-transporting ATPase A chain; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds and transports the potassium across the cytoplasmic membrane.
   
  
 0.668
sll1428
P3 protein; ORF_ID:sll1428.
   
  
 0.660
slr1595
Na/H antiporter; Na(+)/H(+) antiporter; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transporter (TC 2.A.37) family.
