STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

TKThymidine kinase. (232 aa)    
Predicted Functional Partners:
Q8SS22_ENCCU
THYMIDYLATE KINASE.
  
 
 0.995
TS-1
Thymidylate synthase 1/2; Belongs to the thymidylate synthase family.
  
 
 0.988
TS-3
Thymidylate synthase 3; Belongs to the thymidylate synthase family.
  
 
 0.988
DUT1
Deoxyuridine 5'-triphosphate nucleotidohydrolase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
  
 
 0.967
DHFR-1
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity).
  
 
 0.946
PYRG_ENCCU
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen.
  
  
 0.878
SHMT-1
Serine hydroxymethyltransferase, cytosolic; Interconversion of serine and glycine. Belongs to the SHMT family.
  
  
 0.870
Q8SQZ1_ENCCU
Triosephosphate isomerase.
     
 0.815
SEC53
Phosphomannomutase; Involved in the synthesis of the GDP-mannose and dolichol- phosphate-mannose required for a number of critical mannosyl transfer reactions; Belongs to the eukaryotic PMM family.
  
 
 0.793
Q8SUB9_ENCCU
Uncharacterized protein.
    
 0.788
