Background

Function
POLD1 is an As the catalytic component of the trimeric (Pol-delta3 complex) and tetrameric DNA polymerase delta complexes (Pol-delta4 complex), plays a crucial role in high fidelity genome replication, including in lagging strand synthesis, and repair. Exhibits both DNA polymerase and 3'- to 5'-exonuclease activities. Requires the presence of accessory proteins POLD2, POLD3 and POLD4 for full activity. Depending upon the absence (Pol-delta3) or the presence of POLD4 (Pol-delta4), displays differences in catalytic activity. Most notably, expresses higher proofreading activity in the context of Pol-delta3 compared with that of Pol-delta4. Although both Pol-delta3 and Pol-delta4 process Okazaki fragments in vitro, Pol-delta3 may be better suited to fulfill this task, exhibiting near-absence of strand displacement activity compared to Pol-delta4 and stalling on encounter with the 5'-blocking oligonucleotides. Pol-delta3 idling process may avoid the formation of a gap, while maintaining a nick that can be readily ligated. Along with DNA polymerase kappa, DNA polymerase delta carries out approximately half of nucleotide excision repair (NER) synthesis following UV irradiation. Under conditions of DNA replication stress, in the presence of POLD3 and POLD4, may catalyze the repair of broken replication forks through break-induced replication (BIR). Involved in the translesion synthesis (TLS) of templates carrying O6-methylguanine, 8oxoG or abasic sites[1][2][3][4][5][6][7][8][9].

Subunit
Component of the tetrameric DNA polymerase delta complex (Pol-delta4), which consists of POLD1/p125, POLD2/p50, POLD3/p66/p68 and POLD4/p12, with POLD1 bearing both DNA polymerase and 3' to 5' proofreading exonuclease activities (PubMed:11595739, PubMed:12522211, PubMed:17317665, PubMed:22801543, PubMed:31449058, PubMed:31629014). Within Pol-delta4, directly interacts with POLD2 and POLD4 (PubMed:11328591, PubMed:12403614, PubMed:16510448). Following genotoxic stress by DNA-damaging agents, such as ultraviolet light and methyl methanesulfonate, or by replication stress induced by treatment with hydroxyurea or aphidicolin, Pol-delta4 is converted into a trimeric form of the complex (Pol-delta3) by POLD4 degradation. Pol-delta3 is the major form at S phase replication sites and DNA damage sites (PubMed:17317665, PubMed:22801543). POLD1 displays different catalytic properties depending upon the complex it is found in (PubMed:17317665). It exhibits higher proofreading activity and fidelity than Pol-delta4, making it particularly well suited to respond to DNA damage (PubMed:19074196, PubMed:20334433). Directly interacts with PCNA, as do POLD3 and POLD4; this interaction stimulates Pol-delta4 polymerase activity (PubMed:11328591, PubMed:12403614, PubMed:12522211, PubMed:16510448, PubMed:24022480, PubMed:24939902). As POLD2 and POLD4, directly interacts with WRNIP1; this interaction stimulates DNA polymerase delta-mediated DNA synthesis, independently of the presence of PCNA. This stimulation may be due predominantly to an increase of initiation frequency and also to increased processivity (PubMed:15670210). Also observed as a dimeric complex with POLD2 (Pol-delta2 complex). Pol-delta2 is relatively insensitive to the PCNA stimulation (2-5-fold) compared to Pol-delta4 that is stimulated by over 50-fold (PubMed:12403614). The DNA polymerase delta complex interacts with POLDIP2; this interaction is probably mediated through direct binding to POLD2 (PubMed:12522211). Interacts with CIAO1 (PubMed:23891004). Interacts with POLDIP2 (PubMed:24191025). Interacts with RFC1 (PubMed:31629014)
