Proliferating Cell Nuclear Antigen: Difference between revisions

Revision as of 01:29, 19 September 2017

Function

Proliferating Cell Nuclear Antigen (PCNA) acts as a DNA sliding clamp by encircling the DNA and linking it to the genome. It is a processivity factor for DNA polymerase (Dpo) δ in eukaryotic cells^[1].

Relevance

PCNA is useful in the diagnosis of high-grade dysplasia^[2].

Structural highlights

p15 regulates DNA replication and repair by binding to PCNA. PCNA-p15 peptide complex shows the and has ^[3].
