Proliferating cell nuclear antigen molecule. Molecular model of human proliferating cell nuclear antigen (PCNA,blue,green and red),complexed with its loader protein (purple,orange,grey and maroon). PCNA is a cofactor for DNA (deoxyribonucleic acid) polymerase delta,an enzyme that synthesises the new strand during DNA replication and repair. PCNA acts as a sliding clamp,helping to hold DNA polymerase delta to the DNA strand. The loader protein loads the clamp onto its DNA template strand | |
