Partial Reconstitution of Human DNA Mismatch Repair In Vitro: Characterization of the Role of Human Replication Protein A
1 Apr 2002
Abstract excerpt
DNA mismatch repair (MMR) is a critical genome-stabilization system. However, the molecular mechanism of MMR in human cells remains obscure because many of the components have not yet been identified. Using a functional in vitro reconstitution system, this study identified three HeLa cell fractions essential for in vitro MMR. These fractions divide human MMR into two distinct stages: mismatch-provoked excision...
