Anti-KARS2 antibodies are protein reagents that detect specific antigens. The KARS2 antigen is another term for the human protein lysyl-tRNA synthetase 1, encoded by the KARS1 gene. The protein is known to catalyze 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. Canonically, it has an amino acid length of 597 residues and a mass of 68 kilodaltons. Its subcellular localization is in the cell membrane, nucleus, cytoplasm, and is secreted. It is widely expressed in many tissue types. The KARS2 protein is a member of the Class-II aminoacyl-tRNA synthetase protein family. Other alias names for KARS2 include CMTRIB, DEAPLE, and DFNB89. Indicated applications for KARS2 antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
