Fig. 2: The link between MMR and HRR.

Emerging studies highlight potential interactions of mechanisms that underly different forms of DNA repair, such as MMR and HRR. Shared core proteins, including RPA, EXO1, RFC, MSH2/3, MLH3, and PMS2, are identified as key players in both pathways, broadening the concept of DNA repair mechanism exclusivity in specific tumor types (Created with BioRender.com).
