General Information
Biological Significance
Proliferating cell nuclear antigen (PCNA) is a 36 kDa molecule that is highly conserved between species. It has been determined that PCNA serves as a co-factor for DNA polymerase delta in S-phase as well as during DNA synthesis associated with mechanisms involved in DNA damage repair. The temporal specificity of PCNA expression makes it an ideal marker for cell proliferation.
