Enables DNA-directed DNA polymerase activity. Predicted to be involved in DNA metabolic process. Predicted to act upstream of or within DNA replication and cellular response to DNA damage stimulus. Predicted to be located in nucleoplasm. Predicted to be active in nucleus and site of double-strand break. Is expressed in muscle tissue; retina; and seminiferous tubule. Orthologous to human POLL (DNA polymerase lambda). [provided by Alliance of Genome Resources, Apr 2022]
