該基因編碼一種與dna聚合酶delta p50亞單位以及增殖細胞核抗原相互作用的蛋白質。編碼蛋白可能在復制叉繞過dna損傷的能力中起作用。選擇性剪接導致多個轉錄變體[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]
