STRINGSTRING
FRS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FRS1" - Beta subunit of cytoplasmic phenylalanyl-tRNA synthetase, forms a tetramer with Frs2p to generate 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

FRS1Beta 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)    
Predicted Functional Partners:
FRS2
Alpha 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)
   
  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
ILS1
Cytoplasmic isoleucine-tRNA synthetase, target of the G1-specific inhibitor reveromycin A (1072 aa)
   
 
  0.975
WRS1
Cytoplasmic tryptophanyl-tRNA synthetase, aminoacylates tryptophanyl-tRNA (432 aa)
   
   
  0.931
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)
   
   
  0.928
KRS1
Lysyl-tRNA synthetase (591 aa)
   
 
  0.925
PRT1
eIF3b subunit of the core complex of translation initiation factor 3 (eIF3), essential for translation; part of a subcomplex (Prt1p-Rpg1p-Nip1p) that stimulates binding of mRNA and tRNA(i)Met to ribosomes; Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is involved in protein synthesis and, together with other initiation factors, stimulates binding of mRNA and methionyl-tRNAi to the 40S ribosome (763 aa)
     
 
  0.915
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)
   
   
  0.908
THS1
Threonyl-tRNA synthetase, essential cytoplasmic protein (734 aa)
   
 
  0.898
ALA1
Cytoplasmic and mitochondrial alanyl-tRNA synthetase, required for protein synthesis; point mutation (cdc64-1 allele) causes cell cycle arrest at G1; lethality of null mutation is functionally complemented by human homolog; Catalyzes the attachment of alanine to tRNA(Ala) in a two-step reaction- alanine is first activated by ATP to form Ala- AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged tRNA(Ala) via its editing domain (958 aa)
