ID:DPOD1_HUMAN DESCRIPTION: RecName: Full=DNA polymerase delta catalytic subunit; EC=2.7.7.7; AltName: Full=DNA polymerase subunit delta p125; 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. CATALYTIC ACTIVITY: Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). COFACTOR: Binds 1 4Fe-4S cluster (By similarity). SUBUNIT: Heterotetramer composed of subunits of 125 kDa, 50 kDa, 66 kDa and 12 kDa. The 125 kDa subunit contains the polymerase active site and most likely the active site for the 3'-5' exonuclease activity. Interacts with WRNIP1. Interacts with POLD4 and PCNA. INTERACTION: P12004:PCNA; NbExp=2; IntAct=EBI-716569, EBI-358311; P49005:POLD2; NbExp=9; IntAct=EBI-716569, EBI-372354; Q9HCU8:POLD4; NbExp=10; IntAct=EBI-716569, EBI-864968; SUBCELLULAR LOCATION: Nucleus. DOMAIN: The CysB motif binds 1 4Fe-4S cluster and is required for the formation of polymerase complexes (By similarity). MISCELLANEOUS: In eukaryotes there are five DNA polymerases: alpha, beta, gamma, delta, and epsilon which are responsible for different reactions of DNA synthesis. SIMILARITY: Belongs to the DNA polymerase type-B family. SIMILARITY: Contains 1 CysA-type zinc finger. WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/pold1/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
