Anti-KRS antibodies are used in antigen-specific immunodetection in biological samples. The target KRS is a known alias name of the protein lysyl-tRNA synthetase 1, encoded by the KARS1 gene in humans. This 597-amino acid residue 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. It is localized to the cell membrane, nucleus, cytoplasm, and is secreted of the cell and features phosphorylated post-translational modifications. It is reported to be widely expressed in many tissue types. Other synonyms for KRS include CMTRIB, DEAPLE, and DFNB89. Indicated applications for KRS antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
