This domain is found towards the N-terminal of DNA polymerase delta catalytic subunit from Saccharomyces cerevisiae (POL3) and similar eukaryotic protein sequences. POL3 is the catalytic component of DNA polymerase delta (DNA polymerase III), which participates in chromosomal DNA replication. This domain shows an alpha-beta configuration [1,6].	Domain

The eukaryotic DNA polymerase delta (Pol delta) participates in genome replication, homologous recombination, DNA repair and damage tolerance [1]. Human Pol delta consists of four subunits: p125, p50, p66 and p12. The first three subunits correspond to the three subunits of S. cerevisiae Pol delta. p50 serves as a scaffold for the assembly of Pol delta by interacting simultaneously with all of the other three subunits. This entry corresponds to the OB fold domain found in the p50 subunit.	Domain
