STRINGSTRING
TRK1 protein (Saccharomyces cerevisiae) - STRING interaction network
"TRK1" - Component of the Trk1p-Trk2p potassium transport system 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

TRK1Component 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)    
Predicted Functional Partners:
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)
     
 
  0.957
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)
       
 
  0.939
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; Potassium-proton antiport (873 aa)
     
 
  0.926
PPZ1
Serine/threonine protein phosphatase Z, isoform of Ppz2p; involved in regulation of potassium transport, which affects osmotic stability, cell cycle progression, and halotolerance; Essential for the maintenance of cell size and integrity in response to osmotic stress (692 aa)
       
 
  0.914
TRK2
Component of the Trk1p-Trk2p potassium transport system; This protein is required for low-affinity potassium transport (889 aa)
       
 
0.879
PPZ2
Serine/threonine protein phosphatase Z, isoform of Ppz1p; involved in regulation of potassium transport, which affects osmotic stability, cell cycle progression, and halotolerance; Essential for the maintenance of cell size and integrity in response to osmotic stress (710 aa)
     
 
  0.871
HAL5
Putative protein kinase; overexpression increases sodium and lithium tolerance, whereas gene disruption increases cation and low pH sensitivity and impairs potassium uptake, suggesting a role in regulation of Trk1p and/or Trk2p transporters; Protein kinase involved in salt tolerance and pH sensitivity, probably by regulating plasma membrane potential and cation influx. Positively controls the TRK1-TRK2 potassium transport system in response to potassium starvation. Stabilizes TRK1 in the plasma membrane by preventing its vacuolar sorting and degradation. Also stabilizes other plasma me [...] (855 aa)
       
 
  0.868
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)
       
 
  0.855
HAL1
Cytoplasmic protein involved in halotolerance; decreases intracellular Na+ (via Ena1p) and increases intracellular K+ by decreasing efflux; expression repressed by Ssn6p-Tup1p and Sko1p and induced by NaCl, KCl, and sorbitol through Gcn4p; Involved in salt tolerance (294 aa)
       
 
  0.833
SIS2
Negative regulatory subunit of protein phosphatase 1 Ppz1p and also a subunit of the phosphopantothenoylcysteine decarboxylase (PPCDC; Cab3p, Sis2p, Vhs3p) complex, which catalyzes the third step of coenzyme A biosynthesis; Component of the phosphopantothenoylcysteine decarboxylase (PPCDC) involved in the coenzyme A synthesis. Acts as an inhibitory subunit of protein phosphatase PPZ1, which is involved in many cellular processes such as G1-S transition or salt tolerance. Also modulates the expression of the ENA1 ATPase (562 aa)
