Gene Information

human ... POLD4(57804)

General description

Mammalian DNA polymerase (Pol) δ contains four subunits, p125, p50, p68, and p12. DNA polymerase δ 4, accessory subunit (POLD4) is the smallest subunit of DNA polymerase δ. POLD4 gene is located on human chromosome 11q13.2.

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

Mammalian DNA polymerase (Pol) δ plays a key role in DNA replication. DNA polymerase δ 4, accessory subunit (POLD4) is involved in cell cycle progression. It helps to maintain the genomic stability of human cells. p12 is essential for the optimal activity of human Pol δ. p12 helps to stabilize Pol holoenzyme. Interaction of p12 with PCNA also aids in stabilizing the Pol-proliferating cell nuclear antigen (PCNA) complex. Lower expression of the POLD4 gene might participate in the progression of lung cancer.

Physical form

Mammalian DNA polymerase delta (pol delta) is essential for DNA replication, though the functions of this smallest subunit of POLD4 have been elusive. We investigated pol delta activities in vitro and found that it was less active in the absence

Genes of the pre-replication, pre-initiation and replisome complexes duplicate the genome from many sites once in a normal cell cycle. This study examines complex components in lung adenocarcinoma (LUAD) closely, correlating changes in the genome and transcriptome with proliferation and

Genomic instability is an important factor in cancer susceptibility, but a mechanistic understanding of how it arises remains unclear. We examined hypothesized contributions of the replicative DNA polymerase δ (pol δ) subunit POLD4 to the generation of genomic instability in
