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

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; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 2 subfamily. (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.
  
 0.999
MSF1
Phenylalanine--tRNA ligase, mitochondrial; 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.
   
 
0.952
VAS1
Valine--tRNA ligase, mitochondrial; Mitochondrial and cytoplasmic valyl-tRNA synthetase; human homolog VARS2 implicated in mitochondrial diseases, can partially complement yeast null mutant; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.849
DED81
Asparagine--tRNA ligase, cytoplasmic; Cytosolic asparaginyl-tRNA synthetase; required for protein synthesis, catalyzes the specific attachment of asparagine to its cognate tRNA; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.832
ILS1
Isoleucine--tRNA ligase, cytoplasmic; Cytoplasmic isoleucine-tRNA synthetase; target of the G1-specific inhibitor reveromycin A.
  
  
 0.824
HTS1
Histidine--tRNA ligase, mitochondrial; Cytoplasmic and mitochondrial histidine tRNA synthetase; efficient mitochondrial localization requires both a presequence and an amino-terminal sequence; mutations in human ortholog HARS2 are associated with Perrault syndrome; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.814
TYS1
Tyrosine--tRNA ligase, cytoplasmic; Cytoplasmic tyrosyl-tRNA synthetase; required for cytoplasmic protein synthesis; interacts with positions 34 and 35 of the tRNATyr anticodon; mutations in human ortholog YARS are associated with Charcot-Marie-Tooth (CMT) neuropathies; human ortholog YARS functionally complements the heat sensitivity of a ts allele; protein abundance increases in response to DNA replication stress; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.769
GLN4
Glutamine--tRNA ligase; Glutamine tRNA synthetase; monomeric class I tRNA synthetase that catalyzes the specific glutaminylation of tRNA(Gln); N-terminal domain proposed to be involved in enzyme-tRNA interactions; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.767
YHR020W
Putative proline--tRNA ligase YHR020W; Prolyl-tRNA synthetase; N-terminal domain shows weak homology to prokaryotic posttransfer editing domain, but does not possess posttransfer editing activity; may interact with ribosomes, based on co-purification experiments.
   
  
 0.747
KRS1
Lysine--tRNA ligase, cytoplasmic; Lysyl-tRNA synthetase.
