RPA1 (human)

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.

Due to the double-strand breaks (DSBs), replication protein A (RPA) will bind to the single-stranded DNA (ssDNA) and recruit ATRIP complex. The RPA70 (RPA1) N-terminus interacts with the ATRIP. (Bhat, K.P. and Cortez, D, 2018) (Maréchal, A. and Zou, L., 2015)

Dueva, R., & Iliakis, G. (2020) stated that ATRIP is one of the prominent RPA-interacting partners, playing a crucial role in the repair mechanism of DNA repairing and DNA damage checkpoints (Zou, Y., Liu, Y., Wu, X., & Shell, S. M., 2006). Moreover, the N-terminus of RPA1 (RPA70) is shown to be binding to the ATRIP protein (Xu, X., et al, 2008). Considering the protein size, we did not use the entire RPA, instead, we chose RPA1, the interacting domain, to design the FRET system.
