STRINGSTRING
PHO84 protein (Saccharomyces cerevisiae) - STRING interaction network
"PHO84" - High-affinity inorganic phosphate 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

PHO84High-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)    
Predicted Functional Partners:
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)
     
 
  0.995
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)
     
   
  0.983
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)
     
 
  0.979
VTC1
Subunit of the vacuolar transporter chaperone (VTC) complex involved in membrane trafficking, vacuolar polyphosphate accumulation, microautophagy and non-autophagic vacuolar fusion; also has mRNA binding activity; 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 (129 aa)
     
   
  0.967
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)
     
   
  0.961
PHO5
Repressible acid phosphatase (1 of 3) that also mediates extracellular nucleotide-derived phosphate hydrolysis; secretory pathway derived cell surface glycoprotein; induced by phosphate starvation and coordinately regulated by PHO4 and PHO2; Partially mediates extracellular nucleotide derived phosphate hydrolysis along with NPP1 and NPP2 (467 aa)
     
   
  0.961
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)
       
 
  0.960
PHO11
One of three repressible acid phosphatases, a glycoprotein that is transported to the cell surface by the secretory pathway; induced by phosphate starvation and coordinately regulated by PHO4 and PHO2 (467 aa)
     
   
  0.948
PHO87
Low-affinity inorganic phosphate (Pi) transporter, involved in activation of PHO pathway; expression is independent of Pi concentration and Pho4p activity; contains 12 membrane-spanning segments; Involved in the uptake of inorganic phosphate (923 aa)
       
 
  0.945
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)
