Anti-Iars antibodies enable researchers to detect and measure the Iars antigen in biological samples. This target is a reported synonym of the IARS1 gene, which encodes isoleucyl-tRNA synthetase 1. This protein is known to function in osteoblast differentiation, among other biological roles. The human version of Iars has a canonical amino acid length of 1262 residues and a protein mass of 144.5 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the cerebellum and cerebral cortex. This target antigen may also be known as GRIDHH. Some Iars antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
