A number of ELISA Kits are available that target polymerase (DNA-directed), delta 4, an alias of the protein, DNA polymerase delta 4, accessory subunit. The human protein, encoded by the gene POLD4, is a member of the DNA polymerase delta subunit 4 family. The protein's cellular localization is indicated to be nuclear. Additional synonyms or past names for this protein may include: POLDS, p12. Homology is conserved in other species, such as Mouse, Rat.
