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

Iars2Isoleucine--tRNA ligase, mitochondrial; Belongs to the class-I aminoacyl-tRNA synthetase family. (1012 aa)    
Predicted Functional Partners:
Eprs
Bifunctional glutamate/proline--tRNA ligase; Multifunctional protein which is primarily part of the aminoacyl-tRNA synthetase multienzyme complex, also know as multisynthetase complex, that 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 (By similarity). The phosphorylation of EPRS1, induced by interferon-gamma, dissociates the protein from the aminoacyl-tRNA synthetase multienzyme complex [...]

Mars
Methionine--tRNA ligase, cytoplasmic; Catalyzes the specific attachment of an amino acid to its cognate tRNA in a 2 step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. Plays a role in the synthesis of ribosomal RNA in the nucleolus; Belongs to the class-I aminoacyl-tRNA synthetase family.

Mars2
Methionine--tRNA ligase, mitochondrial; Belongs to the class-I aminoacyl-tRNA synthetase family.

Pars2
Probable proline--tRNA ligase, mitochondrial; Belongs to the class-II aminoacyl-tRNA synthetase family.
   
 
 0.984
Rars2
Probable arginine--tRNA ligase, mitochondrial; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 
 0.983
Lars
Leucine--tRNA ligase, cytoplasmic; Catalyzes the specific attachment of an amino acid to its cognate tRNA in a two step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. Exhibits a post-transfer editing activity to hydrolyze mischarged tRNAs; Belongs to the class-I aminoacyl-tRNA synthetase family.

Lars2
Probable leucine--tRNA ligase, mitochondrial; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 
0.981
Kars
Lysine--tRNA ligase; Catalyzes the specific attachment of an amino acid to its cognate tRNA in a 2 step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. When secreted, acts as a signaling molecule that induces immune response through the activation of monocyte/macrophages. Catalyzes the synthesis of the signaling molecule diadenosine tetraphosphate (Ap4A), and thereby mediates disruption of the complex between HINT1 and MITF and the concomitant activation of MITF transcriptional activity; Belongs to the class-I [...]

Qars
Glutamine--tRNA ligase; Glutamine--tRNA ligase. Plays a critical role in brain development; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 0.970
Rars
Arginine--tRNA ligase, cytoplasmic; Forms part of a macromolecular complex that catalyzes the attachment of specific amino acids to cognate tRNAs during protein synthesis. Modulates the secretion of AIMP1 and may be involved in generation of the inflammatory cytokine EMAP2 from AIMP1.
