Product Info
Background The evolutionarily conserved protein PCNA, or cyclin, was first characterized as a DNA polymerase accessory protein. It functions as a DNA sliding clamp for DNA polymerase delta and epsilon, and is an key component of for eukaryotic chromosomal DNA replication (1-3). In more recent research PCNA has been linked to an increasing number of cellular functions, these include cell cycle regulation, DNA repair, Okazaki fragment joining, DNA methylation, and chromatin assembly (2,4, &5). In cell cycle regulation p21 interacts with PCNA, which inhibits DNA replication (2,5). It has also been described that high levels of PCNA in the presence of p53 will lead to DNA repair (4). PCNA is also a very useful marker of cellular proliferation as it is seen most prominently expressed during the S phase of the cell cycle (6).
