To further design a system that can detect DNA breaks in vivo, we proposed a FRET (Förster resonance energy transfer) system using the interaction between ATRIP and RPA1. The ATR (ATMand Rad3-related) and ATRIP (ATR-Interacting protein) form a complex under the circumstances of DNA damage (Qinhui Rao et. al., 2017) (Nam, E. A., & Cortez, D., 2011). Due to the double-strand breaks (DSBs), replication protein A (RPA) will bind to the single-stranded DNA (ssDNA) and recruit ATRIP complex. An earlier research (Zou, L., & Elledge, S. J., 2003) demonstrated that the RPA-ssDNA-ATRIP interaction is important in checkpoint signaling. To be specific, the RPA70 (RPA1) N-terminus interacts with the ATRIP N-termius (Ball, H. L., Myers, J. S., & Cortez, D., 2005).
