Anti-polymerase (DNA) nu antibodies enable researchers to detect and measure the polymerase (DNA) nu antigen in biological samples. This target is a reported synonym of the POLN gene, which encodes DNA polymerase nu. This protein is known to function in DNA replication and DNA repair, among other biological roles. The human version of polymerase (DNA) nu has a canonical amino acid length of 900 residues and a protein mass of 100.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. polymerase (DNA) nu is a member of the DNA polymerase type-A protein family.
