Secondary Accession Numbers
  • 5885
Name Lysine--tRNA ligase
Synonyms
  1. LysRS
  2. Lysine--tRNA ligase
  3. Lysyl-tRNA synthetase
Gene Name KARS
Protein Type Enzyme
Biological Properties
General Function Involved in nucleotide binding
Specific Function 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 diadenosine oligophosphate (Ap4A), a signaling molecule involved in the activation of MITF transcriptional activity. Interacts with HIV-1 virus GAG protein, facilitating the selective packaging of tRNA(3)(Lys), the primer for reverse transcription initiation.
