Nucleic. Acids. Res. 34, 4126-4137 (2006) ATR colocalizes with RPA to nuclear foci after DNA damage
96% 27% The recruitment of ATR and ATRIP to the damage-induced nuclear foci is dependent upon RPA.

U2OS RPAregulates activation of ATR respond to not only replication blocks but also DNA damage.
RPA confers upon ATRIP a higher affinity to ssDNA than to dsDNA or to the ends of dsDNA
The binding of ATRIP to RPA-coated ssDNA is length-dependent with a threshold length between 50 and 75 not that renders ATRIP binding more efficient. EMBO J. 20, 612-618 (2001)
The affinity of ATR for ssDNA is obscuredin the ATR-ATRIP complex The vast majority of ATR is present in complexes with ATRIP in human cells
