Splet20. nov. 2007 · DNA mismatch repair (MMR) is a highly conserved biological pathway that plays a key role in maintaining genomic stability. Defects in MMR predispose to cancers. ... Similarly, proliferating cellular nuclear antigen (PCNA) was found to be essential for MMR by participating both the MMR initiation and repair resynthesis reactions. Splet05. nov. 2007 · Abstract. Mismatch Repair (MMR) is closely linked to DNA replication; however, other than the role of the replicative sliding clamp (PCNA) in various MMR functions, the linkage between DNA replication and MMR has been difficult to investigate.
