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

PRPS2Ribose-phosphate pyrophosphokinase 2; Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis; Belongs to the ribose-phosphate pyrophosphokinase family. (321 aa)    
Predicted Functional Partners:
PRPS1
Ribose-phosphate pyrophosphokinase 1; Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis; Belongs to the ribose-phosphate pyrophosphokinase family.
  
0.985
PRPSAP1
Phosphoribosyl pyrophosphate synthase-associated protein 1; Seems to play a negative regulatory role in 5-phosphoribose 1-diphosphate synthesis.
  
0.985
PRPSAP2
Phosphoribosyl pyrophosphate synthase-associated protein 2; Seems to play a negative regulatory role in 5-phosphoribose 1-diphosphate synthesis.
  
0.981
PPAT
Amidophosphoribosyltransferase; Phosphoribosyl pyrophosphate amidotransferase; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.975
TKT
Transketolase; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate; Belongs to the transketolase family.
   
 
 0.958
RPIA
Ribose 5-phosphate isomerase A; Belongs to the ribose 5-phosphate isomerase family.
  
 
 0.957
RBKS
Ribokinase; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway. Belongs to the carbohydrate kinase PfkB family. Ribokinase subfamily.
  
 0.957
TKTL2
Transketolase-like protein 2; Plays an essential role in total transketolase activity and cell proliferation in cancer cells; after transfection with anti-TKTL1 siRNA, total transketolase activity dramatically decreases and proliferation was significantly inhibited in cancer cells. Plays a pivotal role in carcinogenesis; Belongs to the transketolase family.
   
 
 0.956
TKTL1
Transketolase-like protein 1; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate; Belongs to the transketolase family.
   
 
 0.956
PGM2
Phosphoglucomutase-2; Catalyzes the conversion of the nucleoside breakdown products ribose-1-phosphate and deoxyribose-1-phosphate to the corresponding 5- phosphopentoses. May also catalyze the interconversion of glucose-1- phosphate and glucose-6-phosphate. Has low glucose 1,6-bisphosphate synthase activity; Belongs to the phosphohexose mutase family.
