STRINGSTRING
VNX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"VNX1" - Calcium/H+ antiporter localized to the endoplasmic reticulum membrane 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

VNX1Calcium/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)    
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)
       
 
  0.912
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)
     
 
  0.881
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)
       
 
  0.878
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)
       
 
  0.855
TRK2
Component of the Trk1p-Trk2p potassium transport system; This protein is required for low-affinity potassium transport (889 aa)
       
 
  0.852
PMR1
High affinity Ca2+/Mn2+ P-type ATPase required for Ca2+ and Mn2+ transport into Golgi; involved in Ca2+ dependent protein sorting and processing; mutations in human homolog ATP2C1 cause acantholytic skin condition Hailey-Hailey disease; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Has a role in the secretory pathway (950 aa)
       
 
  0.804
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)
           
  0.801
YDL206W
Putative protein of unknown function; YDL206W is not an essential protein; Putative cation exchanger (762 aa)
     
   
  0.760
YLH47
Mitochondrial inner membrane protein exposed to the mitochondrial matrix, associates with mitochondrial ribosomes, NOT required for respiratory growth; homolog of human Letm1, a protein implicated in Wolf-Hirschhorn syndrome; Involved in mitochondrial potassium homeostasis through the mitochondrial K(+)/H(+) exchange regulation (454 aa)
           
  0.680
FAB1
1-phosphatidylinositol-3-phosphate 5-kinase; vacuolar membrane kinase that generates phosphatidylinositol (3,5)P2, which is involved in vacuolar sorting and homeostasis; The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo- inositol ring, to form phosphatidylinositol 3,5-bisphosphate. Required for endocytic-vacuolar pathway and nuclear migration. The product of the reaction it catalyzes functions as an importa [...] (2278 aa)
