Summaries for TARS3 Gene

GeneCards Summary for TARS3 Gene

TARS3 (Threonyl-TRNA Synthetase 3) is a Protein Coding gene. Diseases associated with TARS3 include Antisynthetase Syndrome. Among its related pathways are tRNA Aminoacylation. An important paralog of this gene is TARS1.

UniProtKB/Swiss-Prot Summary for TARS3 Gene

  • Catalyzes the attachment of threonine to tRNA(Thr) in a two-step reaction: threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged tRNA(Thr) via its editing domain, at the post-transfer stage.
