STRINGSTRING
FRS2 protein (Saccharomyces cerevisiae) - STRING interaction network
"FRS2" - Alpha subunit of cytoplasmic phenylalanyl-tRNA synthetase, forms a tetramer with Frs1p to form active enzyme 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

FRS2Alpha subunit of cytoplasmic phenylalanyl-tRNA synthetase, forms a tetramer with Frs1p to form active enzyme; evolutionarily distant from mitochondrial phenylalanyl-tRNA synthetase based on protein sequence, but substrate binding is similar (503 aa)    
Predicted Functional Partners:
FRS1
Beta subunit of cytoplasmic phenylalanyl-tRNA synthetase, forms a tetramer with Frs2p to generate active enzyme; able to hydrolyze mis-aminoacylated tRNA-Phe, which could contribute to translational quality control (595 aa)
   
  0.999
MSF1
Mitochondrial phenylalanyl-tRNA synthetase, active as a monomer, unlike the cytoplasmic subunit which is active as a dimer complexed to a beta subunit dimer; similar to the alpha subunit of E. coli phenylalanyl-tRNA synthetase; Is responsible for the charging of tRNA(Phe) with phenylalanine in mitochondrial translation (469 aa)
   
  0.999
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)
   
  0.989
DED81
Cytosolic asparaginyl-tRNA synthetase, required for protein synthesis, catalyzes the specific attachment of asparagine to its cognate tRNA (554 aa)
     
   
  0.891
THS1
Threonyl-tRNA synthetase, essential cytoplasmic protein (734 aa)
   
 
  0.881
ILS1
Cytoplasmic isoleucine-tRNA synthetase, target of the G1-specific inhibitor reveromycin A (1072 aa)
   
 
  0.869
SHE2
RNA-binding protein that binds specific mRNAs and interacts with She3p; part of the mRNA localization machinery that restricts accumulation of certain proteins to the bud; RNA-binding protein that binds specific mRNAs including the ASH1 mRNA, coding for a repressor of the HO endonuclease. Part of the mRNA localization machinery that restricts accumulation of certain proteins to the bud and in the daughter cell. Recruits the MYO4-SHE3 complex to the ASH1 mRNA. Recruits also LOC1 and PUF6 to ASH1 mRNA, which are required for translational repression of this mRNA (246 aa)
       
      0.868
GUA1
GMP synthase; highly conserved enzyme that catalyzes the second step in the biosynthesis of GMP from inosine 5’-phosphate (IMP); transcription is not subject to regulation by guanine but is negatively regulated by nutrient starvation; reduction-of-f /.../n mutation gua1-G388D causes changes in cellular guanine nucleotide pools, defects in general protein synthesis, and impaired translation of GCN4 mRNA (525 aa)
   
   
  0.843
ARO1
Pentafunctional arom protein, catalyzes steps 2 through 6 in the biosynthesis of chorismate, which is a precursor to aromatic amino acids; The AROM polypeptide catalyzes 5 consecutive enzymatic reactions in prechorismate polyaromatic amino acid biosynthesis (1588 aa)
   
   
  0.793
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)
     
   
  0.787
