Gene Summary

  • Human (5424): The DNA polymerase delta complex is involved in DNA replication and repair, and it consists of the proliferating cell nuclear antigen (PCNA; MIM 176740), the multisubunit replication factor C (see MIM 102579), and the 4 subunit polymerase complex: POLD1, POLD2 (MIM 600815), POLD3 (MIM 611415), and POLD4 (MIM 611525) (Liu and Warbrick, 2006 [PubMed 16934752]).[supplied by OMIM]
  • Rat (59294): has DNA polymerase and 3'exonuclease activities; plays roles in DNA replication, base excision repair, and other types of DNA repair [RGD]
