STRINGSTRING
KHA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"KHA1" - Putative K+/H+ antiporter with a probable role in intracellular cation homeostasis, localized to Golgi vesicles and detected in highly purified mitochondria in high-throughput studies in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

KHA1Putative K+/H+ antiporter with a probable role in intracellular cation homeostasis, localized to Golgi vesicles and detected in highly purified mitochondria in high-throughput studies; Potassium-proton antiport (873 aa)    
Predicted Functional Partners:
NHX1
Na+/H+ and K+/H+ exchanger, required for intracellular sequestration of Na+ and K+; located in the vacuole and late endosome compartments; required for osmotolerance to acute hypertonic shock and for vacuolar fusion; Endosomal/prevacuolar electroneutral Na(+)/H(+) exchanger which mediates intracellular sequestration of Na(+) cations, regulates vacuolar pH and contributes to osmotolerance following sudden exposure to hyperosmotic media. Contributes also to the postdiauxic/stationary phase resistance to osmotic stress and allows for the continued growth of cells until the acquired osmoto [...] (633 aa)
     
 
  0.975
NHA1
Na+/H+ antiporter involved in sodium and potassium efflux through the plasma membrane; required for alkali cation tolerance at acidic pH; Sodium export from cell, takes up external protons in exchange for internal sodium ions (985 aa)
     
 
  0.974
TRK1
Component of the Trk1p-Trk2p potassium transport system; 180 kDa high affinity potassium transporter; phosphorylated in vivo and interacts physically with the phosphatase Ppz1p, suggesting Trk1p acitivy is regulated by phosphorylation; This protein is required for high-affinity potassium transport (1235 aa)
     
 
  0.926
ENA1
P-type ATPase sodium pump, involved in Na+ and Li+ efflux to allow salt tolerance; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of the sodium or lithium ions to allow salt tolerance. Is negatively modulated by SIS2/HAL3 (1091 aa)
     
 
  0.923
TRK2
Component of the Trk1p-Trk2p potassium transport system; This protein is required for low-affinity potassium transport (889 aa)
     
 
  0.880
VNX1
Calcium/H+ antiporter localized to the endoplasmic reticulum membrane; member of the calcium exchanger (CAX) family; potential Cdc28p substrate; Has a role in promoting intracellular monovalent cation sequestration via the exchange of monovalent cations and especially Na(+) for hydrogen ions across the vacuolar membrane (908 aa)
           
  0.801
TOK1
Outward-rectifier potassium channel of the plasma membrane with two pore domains in tandem, each of which forms a functional channel permeable to potassium; carboxy tail functions to prevent inner gate closures; target of K1 toxin; Outwardly rectifying potassium channel (691 aa)
   
   
  0.796
YDL206W
Putative protein of unknown function; YDL206W is not an essential protein; Putative cation exchanger (762 aa)
         
  0.765
ARL1
Soluble GTPase with a role in regulation of membrane traffic; regulates potassium influx; G protein of the Ras superfamily, similar to ADP-ribosylation factor; Recruits golgins such as IMH1 to the Golgi. Can bind and hydrolyze GTP. May be involved in trafficking events within the endosomal system (183 aa)
       
 
  0.736
QDR2
Multidrug transporter of the major facilitator superfamily, required for resistance to quinidine, barban, cisplatin, and bleomycin; may have a role in potassium uptake; Multidrug resistance transporter involved in resistance and adaptation to quinidine and to the herbicide barban (4-chloro- 2-butynyl [3-chlorophenyl] carbamate). Implicated in potassium uptake (542 aa)
