This event was induced at damaged site to repress local transcription from taking place [76,77], and achieved mainly through recruiting DNMT1 and the DNMT3s and introducing repressive histone modifications including H3K9me2/3 and H3K27me3 at the repair site [75,77]. Li,H., Xie,B., As the catalytic component of the trimeric (Pol-delta3 complex) and tetrameric DNA polymerase delta complexes (Pol-delta4 complex), plays a crucial role in high fidelity genome replication, including in lagging strand synthesis, and repair.

Huang,M.E., de In addition to being associated with PCNA at replication sties, DNMT1 also interacts with PCNA at DNA-damage sites [63] where MLH1 is also recruited [64], to methylate the new strand, demonstrating another aspect of DNMT1’s role in MMR [63]. It prevents global demethylation and epigenetic information loss by activating checkpoint pathways while being physically absent from the replication fork.
