Summary: Enables 3'-5' exonuclease activity and enzyme binding activity. Involved in DNA biosynthetic process. Acts upstream of or within DNA replication proofreading and base-excision repair, gap-filling. Part of delta DNA polymerase complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human POLD1 (DNA polymerase delta 1, catalytic subunit). [provided by Alliance of Genome Resources, Apr 2025]

A point mutation (D400A) in the proofreading domain of DNA polymerase delta, encoded by the Pold1 gene, inactivates the 3' --> 5' exonuclease of poldelta and causes a mutator and epithelial cancer phenotype in a recessive manner.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
