STRINGSTRING
TPO5 protein (Saccharomyces cerevisiae) - STRING interaction network
"TPO5" - Protein involved in excretion of putrescine and spermidine 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

TPO5Protein involved in excretion of putrescine and spermidine; putative polyamine transporter in the Golgi or post-Golgi vesicles; Required for polyamine transport. Transports putrescine effectively and spermidine less effectively (618 aa)    
Predicted Functional Partners:
DUR1,2
Urea amidolyase, contains both urea carboxylase and allophanate hydrolase activities, degrades urea to CO2 and NH3; expression sensitive to nitrogen catabolite repression and induced by allophanate, an intermediate in allantoin degradation; Hydrolysis of urea to ammonia and CO(2) (1835 aa)
   
   
  0.759
DUR3
Plasma membrane transporter for both urea and polyamines, expression is highly sensitive to nitrogen catabolite repression and induced by allophanate, the last intermediate of the allantoin degradative pathway; Required for active transport of urea (735 aa)
     
   
  0.728
TPO1
Polyamine transporter that recognizes spermine, putrescine, and spermidine; catalyzes uptake of polyamines at alkaline pH and excretion at acidic pH; phosphorylation enhances activity and sorting to the plasma membrane; Cell membrane polyamine/proton antiporter, involved in the detoxification of excess polyamines in the cytoplasm. Catalyzes polyamine uptake at alkaline pH and excretion at acidic pH. Recognizes spermidine, spermine and putrescine, the polyamine analogs methylglyoxal bis(guanylhydrazone) (MGBG) and paraquat, the antimalarial drug quinidine, and cycloheximide. Confers res [...] (586 aa)
   
 
  0.643
SAM3
High-affinity S-adenosylmethionine permease, required for utilization of S-adenosylmethionine as a sulfur source; has similarity to S-methylmethionine permease Mmp1p; High-affinity S-adenosylmethionine permease, required for utilization of S-adenosylmethionine as a sulfur source (587 aa)
           
  0.640
HOM3
Aspartate kinase (L-aspartate 4-P-transferase); cytoplasmic enzyme that catalyzes the first step in the common pathway for methionine and threonine biosynthesis; expression regulated by Gcn4p and the general control of amino acid synthesis (527 aa)
     
 
  0.614
SPE1
Ornithine decarboxylase, catalyzes the first step in polyamine biosynthesis; degraded in a proteasome-dependent manner in the presence of excess polyamines; deletion decreases lifespan, and increases necrotic cell death and ROS generation (466 aa)
   
   
  0.603
TPO2
Polyamine transport protein specific for spermine; localizes to the plasma membrane; transcription of TPO2 is regulated by Haa1p; member of the major facilitator superfamily; Cell membrane polyamine/proton antiporter, involved in the detoxification of excess polyamines in the cytoplasm. Recognizes spermine, but not spermidine (614 aa)
   
 
  0.591
HOM6
Homoserine dehydrogenase (L-homoserine-NADP oxidoreductase), dimeric enzyme that catalyzes the third step in the common pathway for methionine and threonine biosynthesis; enzyme has nucleotide-binding, dimerization and catalytic regions (359 aa)
       
 
  0.588
TRP4
Anthranilate phosphoribosyl transferase of the tryptophan biosynthetic pathway, catalyzes the phosphoribosylation of anthranilate, subject to the general control system of amino acid biosynthesis (380 aa)
       
 
  0.583
TPO3
Polyamine transport protein specific for spermine; localizes to the plasma membrane; member of the major facilitator superfamily; Cell membrane polyamine/proton antiporter, involved in the detoxification of excess polyamines in the cytoplasm. Recognizes spermine, but not spermidine (622 aa)
