Ready-to-use ELISA kits are available for the detection of prolyl-tRNA synthetase (mitochondrial)(putative), an alias of the protein, prolyl-tRNA synthetase 2, mitochondrial. The official gene symbol is PARS2. The protein, with a mass of 53.3 kDa and length of 475 residues, is reported to be mitochondrial. It is a member of the Class-II aminoacyl-tRNA synthetase family and may be known by other names, including: proRS, EIEE75, prolyl-tRNA synthetase 2 mitochondrial (putative), proline tRNA ligase 2 mitochondrial (putative), and probable proline--tRNA ligase mitochondrial.
