  • FunctionForms 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.
  • Sequence similaritiesBelongs to the class-I aminoacyl-tRNA synthetase family.
  • DomainThe N-terminus (AA 1-72) has two regions predicted to be alpha-helical that might be involved in the multisynthetase complex assembly.
  • Cellular localizationCytoplasm.
  • Information by UniProt
  • Database links
  • FormThere are 2 isoforms produced by alternative initiation.
