STRINGSTRING
GLN4 protein (Saccharomyces cerevisiae) - STRING interaction network
"GLN4" - Glutamine tRNA synthetase, monomeric class I tRNA synthetase that catalyzes the specific glutaminylation of tRNA(Glu) in Saccharomyces cerevisiae
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

GLN4Glutamine tRNA synthetase, monomeric class I tRNA synthetase that catalyzes the specific glutaminylation of tRNA(Glu); N-terminal domain proposed to be involved in enzyme-tRNA interactions (809 aa)    
Predicted Functional Partners:
MES1
Methionyl-tRNA synthetase, forms a complex with glutamyl-tRNA synthetase (Gus1p) and Arc1p, which increases the catalytic efficiency of both tRNA synthetases; also has a role in nuclear export of tRNAs; Catalyzes the attachment of methionine to tRNA(Met) in a two-step reaction- methionine is first activated by ATP to form Met-AMP and then transferred to the acceptor end of tRNA(Met) (751 aa)
   
 
  0.998
ILS1
Cytoplasmic isoleucine-tRNA synthetase, target of the G1-specific inhibitor reveromycin A (1072 aa)
   
 
  0.997
PET112
Subunit of the trimeric GatFAB AmidoTransferase(AdT) complex; involved in the formation of Q-tRNAQ; mutation is functionally complemented by the bacterial GatB ortholog; 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) (541 aa)
   
  0.997
YDR341C
Arginyl-tRNA synthetase, proposed to be cytoplasmic but the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies; Forms part of a macromolecular complex that catalyzes the attachment of specific amino acids to cognate tRNAs during protein synthesis (607 aa)
   
 
  0.996
MSR1
Mitochondrial arginyl-tRNA synthetase (643 aa)
   
 
  0.995
ARC1
Protein that binds tRNA and methionyl- and glutamyl-tRNA synthetases (Mes1p and Gus1p), delivering tRNA to them, stimulating catalysis, and ensuring their localization to the cytoplasm; also binds quadruplex nucleic acids; Binds to tRNA and functions as a cofactor for the methionyl-tRNA synthetase (MetRS) and glutamyl-tRNA synthetase (GluRS). Forms a complex with MetRS and GluRS and increases their affinity for cognate tRNAs due to the presence of a tRNA binding domain in its middle and C-terminal part. Binds specifically G4 quadruplex nucleic acid structures (these are four-stranded r [...] (376 aa)
   
 
  0.994
HER2
Subunit of the trimeric GatFAB AmidoTransferase(AdT) complex; involved in the formation of Q-tRNAQ; required for remodeling of ER caused by Hmg2p overexpression; similar to bacterial GatA glutamyl-tRNA amidotransferase; 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). Required for HMG2-induced ER-remodeling (464 aa)
   
  0.993
CDC60
Cytosolic leucyl tRNA synthetase, ligates leucine to the appropriate tRNA (1090 aa)
   
 
  0.991
YHR020W
Protein of unknown function that may interact with ribosomes, based on co-purification experiments; has similarity to proline-tRNA ligase; YHR020W is an essential gene (688 aa)
 
 
  0.990
MSM1
Mitochondrial methionyl-tRNA synthetase (MetRS), functions as a monomer in mitochondrial protein synthesis; functions similarly to cytoplasmic MetRS although the cytoplasmic form contains a zinc-binding domain not found in Msm1p (575 aa)
