Anti-TP73 antibodies are used in the immunodetection of the protein tumor protein p73. In humans, the canonical protein has a reported length of 636 amino acid residues and a mass of 69.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 12 different isoforms have been reported for this protein. It is reported to be expressed in striatal neurons of patients with Huntington disease. A member of the P53 protein family, TP73 is known to participate in the apoptotic response to DNA damage. Post-translational modifications have been described, including ubiquitination, sumoylation and phosphorylation. Synonyms for this target antigen include P73, p53-like transcription factor, p53-related protein, and CILD47. TP73 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 260 citations in the literature describe the use of TP73 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
