Anti-REV3-like, polymerase (DNA directed), zeta, catalytic subunit antibodies are used in antigen-specific immunodetection in biological samples. The target REV3-like, polymerase (DNA directed), zeta, catalytic subunit is a known alias name of the protein REV3 like, DNA directed polymerase zeta catalytic subunit, encoded by the REV3L gene in humans. This 3130-amino acid residue protein is a known catalytic subunit of the DNA polymerase zeta complex, an error-prone polymerase specialized in translesion DNA synthesis (TLS). It is localized to the nucleus of the cell. In terms of tissue expression, it is ubiquitously expressed across many tissue types. Other synonyms for REV3-like, polymerase (DNA directed), zeta, catalytic subunit include POLZ, REV3, and DNA polymerase zeta catalytic subunit.
