Anti-TOB1 antibodies are used in the immunodetection of the protein transducer of ERBB2, 1. In humans, the canonical protein has a reported length of 345 amino acid residues and a mass of 38.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the BTG protein family, TOB1 is known to be involved with the regulation of cell proliferation and the regulation of cell differentiation. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include APRO6, PIG49, TOB, TROB, TROB1, protein Tob1, proliferation-inducing gene 49, and APRO5. TOB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Tob1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
