The POLD2 protein is a key component of DNA polymerase delta (Pol-delta) and DNA polymerase zeta (Pol-zeta) complexes, which are essential for genome replication fidelity and repair. In Pol-delta3 and Pol-delta4 forms, POLD2 contributes to high-fidelity lagging strand synthesis. POLD2 Protein, Human (His) is the recombinant human-derived POLD2, expressed by E. coli, with C-6*His labeled tag.
