Anti-FAU antibodies are used in the immunodetection of the protein FAU ubiquitin like and ribosomal protein S30 fusion. In humans, the canonical protein has a reported length of 133 amino acid residues and a mass of 14.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the Ubiquitin protein family; Eukaryotic ribosomal protein eS30 protein family, FAU is known to be involved with protein translation. Post-translational modifications have been described, including protein cleavage. Synonyms for this target antigen include Fub1, Fubi, MNSFbeta, RPS30, S30, asr1, eS30, and FAU1. FAU gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some FAU 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.
