Sustained poly(ADP-ribosyl)ation limits RPA loading and attenuates ATR-CHK1 signaling upon replication fork collapse

Alexandra Mihuț, Debanjan Ghosh, Dávid Szüts, Roberta Fajka‐Boja, Gyula Timinszky

This study shows that sustained PARylation reduces RPA loading and dampens ATR-CHK1 signaling during replication fork collapse, linking PARP activity to checkpoint control.
