Anti-PTOV1 antibodies are used in the immunodetection of the protein PTOV1 extended AT-hook containing adaptor protein. In humans, the canonical protein has a reported length of 416 amino acid residues and a mass of 46.9 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in the brain, heart, kidney, liver, placenta, skeletal muscle and small intestine. A member of the Mediator complex subunit 25 protein family, PTOV1 is believed to activate transcription. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include prostate tumor-overexpressed gene 1 protein, activator interaction domain-containing protein 2, prostate tumor overexpressed 1, and ACID2. PTOV1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some PTOV1 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.
