Secondary Accession Numbers
  • 6246
Name DNA polymerase delta catalytic subunit
Synonyms
  1. DNA polymerase subunit delta p125
Gene Name POLD1
Protein Type Enzyme
Biological Properties
General Function Involved in nucleotide binding
Specific Function Possesses two enzymatic activities: DNA synthesis (polymerase) and an exonucleolytic activity that degrades single stranded DNA in the 3'- to 5'-direction. Required with its accessory proteins (proliferating cell nuclear antigen (PCNA) and replication factor C (RFC) or activator 1) for leading strand synthesis. Also involved in completing Okazaki fragments initiated by the DNA polymerase alpha/primase complex.
