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

burBurgundy, isoform B; Burgundy (bur) encodes a GMP synthetase required for axon guidance. It regulates the activity of the ubiquitin protease encoded by Usp7. (683 aa)    
Predicted Functional Partners:
ras
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.
 
 0.998
Usp7
Ubiquitin carboxyl-terminal hydrolase 7; Hydrolase that deubiquitinates target proteins.
   
 
 0.993
Aprt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.993
CTPsyn
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Constitutes the rate-limiting enzyme in the synthesis of cytosine nucleotides (By similarity). Isoform 1 is required for cytoophidium assembly in female germline cells.
  
 
 0.976
CG8891
Inosine triphosphate pyrophosphatase; Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) or 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.
  
 
 0.969
CG11811
GH06691p; Guanylate kinase activity. It is involved in the biological process described with: purine nucleotide metabolic process.
  
 
 0.958
Pfas
Phosphoribosylformylglycinamidine synthase (Pfas) encodes a phosphoribosylformylglycinamidine synthase, which is an essential enzyme in the pathway for de novo synthesis of the purine nucleotide inosine monophosphate (IMP). IMP is the precursor for purine nucleotides required for nucleic acids, energy transfer, cell signaling, and coenzymes; In the N-terminal section; belongs to the FGAMS family.
  
  
 0.940
GluProRS
Bifunctional glutamate/proline--tRNA ligase; Catalyzes the attachment of the cognate amino acid to the corresponding tRNA in a two-step reaction: the amino acid is first activated by ATP to form a covalent intermediate with AMP and is then transferred to the acceptor end of the cognate tRNA. In the C-terminal section; belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.932
LysRS
Lysine--tRNA ligase; tRNA binding; ATP binding; lysine-tRNA ligase activity. It is involved in the biological process described with: lysyl-tRNA aminoacylation.
  
  
 0.927
NTPase
NTPase, isoform F; Uridine-diphosphatase activity; guanosine-diphosphatase activity; Belongs to the GDA1/CD39 NTPase family.
   
 
 0.925
