Anti-PDZRN3 antibodies are used in the immunodetection of the protein PDZ domain containing ring finger 3. In humans, the canonical protein has a reported length of 1066 amino acid residues and a mass of 119.6 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be widely expressed including in the heart, skeletal muscle and liver and, at lower levels, in the brain, colon, small intestine, placenta and lung. PDZRN3 is known to be involved with protein ubiquitination. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include SEMACAP3, SEMCAP3, E3 ubiquitin-protein ligase PDZRN3, RING-type E3 ubiquitin transferase PDZRN3, and LNX3. PDZRN3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PDZRN3 antibodies may have been used in research and have associated citations. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
