Anti-DTX4 antibodies are used in the immunodetection of the protein deltex E3 ubiquitin ligase 4. In humans, the canonical protein has a reported length of 619 amino acid residues and a mass of 67.3 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 bronchus, thyroid gland, and appendix. A member of the Deltex protein family, DTX4 is a reported regulator of notch signaling, a signaling pathway involved in cell-cell communications that regulates a broad spectrum of cell-fate determinations (By similarity). Synonyms for this target antigen include E3 ubiquitin-protein ligase DTX4, RING finger protein 155, RING-type E3 ubiquitin transferase DTX4, deltex 4 homolog, deltex 4, E3 ubiquitin ligase, and RNF155. DTX4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some DTX4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
