Gene Information

human ... POLD4(57804)

General description

DNA polymerase δ 4 (POLD4), also known as p12, is the smallest subunit of DNA polymerase (Pol) δ. It is encoded by the gene mapped to human chromosome 11q13.2.
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 (MIM 174761), POLD2 (MIM 600815), POLD3 (MIM 611415), and POLD4 (Liu and Warbrick, 2006 [PubMed 16934752]).

Immunogen

POLD4 (AAH01334, 1 a.a. ~ 34 a.a) full-length recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

DNA polymerase (Pol) δ plays a vital role in DNA replication, DNA repair processes and genetic recombination. POLD4 stabilizes the Pol δ holoenzyme. In addition, it also facilitates pol δ-PCNA complex stabilization. Proteolysis of POLD4 in response to DNA damage leads to the consequent conversion of the holoenzyme pol δ4 to the heterotrimer pol δ3. Pol δ3 acts as an antimutator polymerase and is supposed to enhance surveillance against mutagenesis. Downregulated expression of the gene is associated with the genomic instability in lung cancer.

Mammalian DNA polymerase (Pol) delta is essential for DNA replication. It consists of four subunits, p125, p50, p68, and p12. We report the discovery that the p12 subunit is rapidly degraded in cultured human cells by DNA damage or replication
