Ready-to-use ELISA kits are available for the detection of polymerase (DNA directed), epsilon 3, accessory subunit, an alias of the protein, DNA polymerase epsilon 3, accessory subunit. The official gene symbol is POLE3. The protein, with a mass of 16.9 kDa and length of 147 residues, is reported to be nuclear. It may be known by other names, including: asTP, arsenic transactivated protein, DNA polymerase epsilon p17 subunit, DNA polymerase II subunit 3, CHRAC-17, and DNA polymerase epsilon subunit 3, and chromatin accessibility complex subunit 2.
