STRINGSTRING
PHO90 protein (Saccharomyces cerevisiae) - STRING interaction network
"PHO90" - Low-affinity phosphate transporter 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

PHO90Low-affinity phosphate transporter; deletion of pho84, pho87, pho89, pho90, and pho91 causes synthetic lethality; transcription independent of Pi and Pho4p activity; overexpression results in vigorous growth; Low-affinity phosphate transporter involved in the control of cellular phosphate levels (881 aa)    
Predicted Functional Partners:
PHO89
Na+/Pi cotransporter, active in early growth phase; similar to phosphate transporters of Neurospora crassa; transcription regulated by inorganic phosphate concentrations and Pho4p; Sodium-phosphate symporter. Active in early growth phase (574 aa)
     
 
  0.917
PHO84
High-affinity inorganic phosphate (Pi) transporter and low-affinity manganese transporter; regulated by Pho4p and Spt7p; mutation confers resistance to arsenate; exit from the ER during maturation requires Pho86p; High-affinity transporter for external inorganic phosphate. Is not an essential protein, since a constitutive, low affinity pI transporter exists in yeast (587 aa)
       
 
  0.910
SPL2
Protein with similarity to cyclin-dependent kinase inhibitors; downregulates low-affinity phosphate transport during phosphate limitation; overproduction suppresses a plc1 null mutation; GFP-fusion protein localizes to the cytoplasm; Putative cyclin-dependent kinase (CDK) inhibitor necessary and sufficient for PHO pathway-dependent down-regulation of low-affinity phosphate transport (148 aa)
       
 
  0.876
PHO4
Basic helix-loop-helix (bHLH) transcription factor of the myc-family; activates transcription cooperatively with Pho2p in response to phosphate limitation; binding to ’CACGTG’ motif is regulated by chromatin restriction, competitive binding of Cbf1p to the same DNA binding motif and cooperation with Pho2p; function is regulated by phosphorylation at multiple sites and by phosphate availability; Transcriptional activator that regulates the expression of repressible phosphatase under phosphate starvation conditions. Binds to the upstream activating sequence (UAS) of several phosphatase e [...] (312 aa)
       
 
  0.848
PHO85
Cyclin-dependent kinase, with ten cyclin partners; involved in regulating the cellular response to nutrient levels and environmental conditions and progression through the cell cycle; Cyclin-dependent protein kinase (CDK) catalytic subunit that regulates multiple cell cycle and metabolic processes in response to nutrient availability. Associates with different cyclins, that control kinase activity, substrate specificity and subcellular location of the kinase. Favorable growth conditions always result in activated cyclin-CDK complexes. Regulates metabolic processes when associated with [...] (305 aa)
       
 
  0.826
PHO81
Cyclin-dependent kinase (CDK) inhibitor, regulates Pho80p-Pho85p and Pcl7p-Pho85p cyclin-CDK complexes in response to phosphate levels; inhibitory activity for Pho80p-Pho85p requires myo-D-inositol heptakisphosphate (IP7) generated by Vip1p; Inhibits the kinase activity of the cyclin-CDKs PHO80- PHO85 and PCL7-PHO85 under low-phosphate conditions (1178 aa)
           
  0.788
VTC3
Subunit of the vacuolar transporter chaperone (VTC) complex involved in membrane trafficking, vacuolar polyphosphate accumulation, microautophagy and non-autophagic vacuolar fusion; Component of the vacuolar transporter chaperone (VTC) complex, which plays a role in vacuolar membrane fusion. Required for LMA1 release prior to membrane fusion (835 aa)
     
   
  0.770
VTC4
Vacuolar membrane polyphosphate polymerase; subunit of the vacuolar transporter chaperone (VTC) complex involved in synthesis and transfer of polyP to the vacuole; regulates membrane trafficking; role in non-autophagic vacuolar fusion; Component of the vacuolar transporter chaperone (VTC) complex, which plays a role in vacuolar membrane fusion. Required for SEC18/NSF activity in SNARE priming, membrane binding of LMA1 and V(0) trans-complex formation (721 aa)
     
   
  0.741
SYG1
Plasma membrane protein of unknown function; truncation and overexpression suppresses lethality of G-alpha protein deficiency; May function in G-protein coupled signal transduction (902 aa)
     
   
  0.727
VTC2
Subunit of the vacuolar transporter chaperone (VTC) complex involved in membrane trafficking, vacuolar polyphosphate accumulation, microautophagy and non-autophagic vacuolar fusion; Component of the vacuolar transporter chaperone (VTC) complex, which plays a role in vacuolar membrane fusion (828 aa)
