  • Function
    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.
  • Sequence similarities
    In the N-terminal section; belongs to the class-I aminoacyl-tRNA synthetase family.
    In the C-terminal section; belongs to the class-II aminoacyl-tRNA synthetase family.
    Contains 3 WHEP-TRS domains.
  • Domain
    The WHEP-TRS domain is involved in RNA binding.
  • Post-translational
    Phosphorylated at Ser-886 by CDK5 in a IFN-gamma-dependent manner; this phosphorylation activates assembly of the GAIT (IFN-gamma-activated inhibitor of translation) complex, which suppresses expression of a post-transcriptional regulon of proinflammatory genes in myeloid cells.
