Target Information
PCNA (Proliferating Cell Nuclear Antigen) is essential for DNA replication and is 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 key marker for proliferative cells and tumor proliferation status. It is localized in the nucleus, acts as a homotrimer, and functions as a cofactor of DNA polymerase delta to enhance DNA synthesis processivity. 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.
