STRINGSTRING
PRPS1 protein (human) - STRING interaction network
"PRPS1" - Ribose-phosphate pyrophosphokinase 1 in Homo sapiens
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

PRPS1Ribose-phosphate pyrophosphokinase 1; Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis; Belongs to the ribose-phosphate pyrophosphokinase family (318 aa)    
Predicted Functional Partners:
PPAT
Amidophosphoribosyltransferase; Phosphoribosyl pyrophosphate amidotransferase; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family (517 aa)
   
  0.987
PRPS2
Ribose-phosphate pyrophosphokinase 2; Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis; Belongs to the ribose-phosphate pyrophosphokinase family (321 aa)
   
0.973
PRPS1L1
Ribose-phosphate pyrophosphokinase 3; Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis (318 aa)
   
 
0.964
PRPSAP2
Phosphoribosyl pyrophosphate synthase-associated protein 2; Seems to play a negative regulatory role in 5- phosphoribose 1-diphosphate synthesis (369 aa)
   
 
0.956
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 (322 aa)
     
  0.949
RPIA
Ribose 5-phosphate isomerase A; Belongs to the ribose 5-phosphate isomerase family (311 aa)
   
  0.949
PRPSAP1
Phosphoribosyl pyrophosphate synthase-associated protein 1; Seems to play a negative regulatory role in 5- phosphoribose 1-diphosphate synthesis (385 aa)
   
 
0.948
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 (631 aa)
   
 
  0.946
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 (626 aa)
   
 
  0.940
NUDT5
ADP-sugar pyrophosphatase; Enzyme that can either act as an ADP-sugar pyrophosphatase in absence of diphosphate or catalyze the synthesis of ATP in presence of diphosphate. In absence of diphosphate, hydrolyzes with similar activities various modified nucleoside diphosphates such as ADP-ribose, ADP-mannose, ADP-glucose, 8-oxo-GDP and 8-oxo-dGDP. Can also hydrolyze other nucleotide sugars with low activity. In presence of diphosphate, mediates the synthesis of ATP in the nucleus by catalyzing the conversion of ADP-ribose to ATP and ribose 5- phosphate. Nuclear ATP synthesis takes place [...] (219 aa)
