This gene encodes a protein that interacts with the DNA polymerase delta p50 subunit. The encoded protein also interacts with proliferating cell nuclear antigen. Some transcripts of this gene overlap in a tail-to-tail orientation with the gene for tumor necrosis factor, alpha-induced protein 1 (TNFAIP1).^[6] POLDIP2 / PDIP38 is a moonlighting protein that has been identified in both the nucleus ^[7] and the mitochondrion ^[8][9]
