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

GMPSGMP synthase [glutamine-hydrolyzing]. (693 aa)    
Predicted Functional Partners:
IMPDH2
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth.
 
 0.991
GMPR
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides.
  
 0.987
APRT
Adenine phosphoribosyltransferase.
  
 0.980
GUK1
Guanylate kinase.
  
 
 0.976
ITPA
Inosine triphosphate pyrophosphatase; Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions; Belongs to the HAM1 NTPase family.
  
 
 0.965
HPRT1
Hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.955
USP7
Ubiquitin carboxyl-terminal hydrolase 7; Belongs to the peptidase C19 family.
   
 
 0.955
GATB
Glutamyl-tRNA(Gln) amidotransferase subunit B, mitochondrial; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in the mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln). Belongs to the GatB/GatE family. GatB subfamily.
  
 
 0.954
ALDH18A1
Delta-1-pyrroline-5-carboxylate synthase; In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.
  
 
 0.950
DHODH
Dihydroorotate dehydrogenase (quinone), mitochondrial; Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily.
  
 0.944
