Anti-mt-TyrRS antibodies enable researchers to detect and measure the mt-TyrRS antigen in biological samples. This target is a reported synonym of the YARS2 gene, which encodes tyrosyl-tRNA synthetase 2. This protein is known to function in protein translation, among other biological roles. The human version of mt-TyrRS has a canonical amino acid length of 477 residues and a protein mass of 53.2 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include CGI-04, MLASA2, and MT-TYRRS.
