These threonyl-tRNA Synthetase-Like 2 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. threonyl-tRNA Synthetase-Like 2 is an alias of the human TARS3 gene, which encodes the protein, threonyl-tRNA synthetase 3. The protein is known to catalyze 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). The TARS3 protein is 802 amino acid residues in length and 92.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include threonine--tRNA ligase 2, cytoplasmic, probable threonine--tRNA ligase 2, cytoplasmic, and probable threonyl-tRNA synthetase 2, cytoplasmic.
