Target Information
PCNA (polymerase delta auxiliary protein) is essential for DNA replication and involved in DNA excision and mismatch repair pathways. It binds to CDK inhibitor p21, endonucleases Fen1 and XPG, and DNA cytosine 5-methyltransferase (MCMT).
PCNA serves as a marker for proliferating cells and is useful for assessing tumor proliferation status. It is localized in the nucleus, acts as a cofactor of DNA polymerase delta, and forms a homotrimer to enhance leading strand synthesis. Upon DNA damage, PCNA is ubiquitinated and participates in the RAD6-dependent DNA repair pathway.
Two transcript variants encoding the same protein have been identified, and pseudogenes exist on chromosome 4 and the X chromosome.
