该基因编码复制因子c的大亚单位，一种五亚单位的dna聚合酶辅助蛋白，是真核dna复制和修复所需的dna依赖性atp酶。大亚单位作为dna聚合酶的激活剂，与引物的3'端结合，促进两条链的协同合成。它也可能在端粒稳定性中起作用另外，编码不同亚型的剪接转录变体已经被注意到。[由RefSeq提供，2011年3月]
This gene encodes the large subunit of replication factor C, a five subunit DNA polymerase accessory protein, which is a DNA-dependent ATPase required for eukaryotic DNA replication and repair. The large subunit acts as an activator of DNA polymerases, binds to the 3' end of primers, and promotes coordinated synthesis of both strands. It may also have a role in telomere stability. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Mar 2011]
