Anti-FARSB antibodies are used in the immunodetection of the protein phenylalanyl-tRNA synthetase subunit beta. In humans, the canonical protein has a reported length of 589 amino acid residues and a mass of 66.1 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the cerebellum and cerebral cortex. A member of the Phenylalanyl-tRNA synthetase beta subunit protein family, FARSB is known to be involved with protein translation. The FARSB gene has been associated with the disease, Rajab interstitial lung disease with brain calcifications. Synonyms for this target antigen include FRSB, HSPC173, NEDBLLA, PheHB, PheRS, RILDBC, RILDBC1, and FARSLB. FARSB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some FARSB antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
