Predicted to enable DNA-directed DNA polymerase activity. Predicted to be involved in double-strand break repair via homologous recombination and error-prone translesion synthesis. Predicted to act upstream of or within DNA repair. Predicted to be located in nucleolus. Predicted to be part of zeta DNA polymerase complex. Predicted to be active in nucleus. Orthologous to human REV3L (REV3 like, DNA directed polymerase zeta catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
