Biochem/physiol Actions

Proliferating cell nuclear antigen-l1 (PCNA) is a member of the scaffold B class. It acts as a linker at the monomer-monomer interface. PCNA-I1 has the ability to block the development of primary cultures of bone marrow mesenchymal stem cells, endothelial cells, lymphocytes, mammary epithelial cells and prostate epithelial cells.
PCNA-I1 is a PCNA inhibitor.
PCNA-I1 is a small molecule PCNA inhibitor that selectively binds to PCNA trimers and reduces the association of PCNA with chromatin. PCNA-I1 induces S and G2/M phase cell cycle arrest in tumor cells with greater efficacy than non-transformed cells.
