POLDIP2（DNA polymerase delta interacting protein 2），癌症关联基因，基因ID：26073，该基因编码一种与dna聚合酶delta p50亚单位以及增殖细胞核抗原相互作用的蛋白质。编码蛋白可能在复制叉绕过dna损伤的能力中起作用。选择性剪接导致多个转录变体[由RefSeq提供，2014年2月]This gene encodes a protein that interacts with the DNA polymerase delta p50 subunit， as well as with proliferating cell nuclear antigen. The encoded protein maybe play a role in the ability of the replication fork to bypass DNA lesions. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Feb 2014]。
