Structure of Proliferating Cell Nuclear Antigen (PCNA) bound to a small molecule inhibitor #225618446
Description
Proliferating cell nuclear antigen PCNA is a DNA clamp that acts as a processivity factor for DNA polymerase ô in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.
