Anti-POLD4 antibodies are used in the immunodetection of the protein DNA polymerase delta 4, accessory subunit. In humans, the canonical protein has a reported length of 107 amino acid residues and a mass of 12.4 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. A member of the DNA polymerase delta subunit 4 protein family, POLD4 is known to be involved with DNA replication. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include DNA polymerase delta smallest subunit p12, polymerase (DNA) delta 4, accessory subunit, polymerase (DNA-directed), delta 4, accessory subunit, and DNA polymerase delta subunit 4. POLD4 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some POLD4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
