The DNA damage response (DDR) is comprised of a network of proteins that respond to DNA damage. Mediator of DNA Damage Checkpoint 1 (MDC1) plays an early and important role in the DDR. Recent data show that MDC1 binds multiple proteins that participate in various aspects of the DDR, positioning it at the core of the DDR. Furthermore, interactions with non-DDR proteins were also revealed, suggesting novel roles for MDC1. In this review we provide a comprehensive overview of all known MDC1-binding proteins and discuss their role. We present these binding partners according to their function, thereby providing the reader with a detailed and updated overview of the cellular response to DNA damage. We discuss more recent findings in detail and conclude by presenting the challenges the field faces in the future.
