ATR and Chk1 are important components of a cell cycle checkpoint pathway. In this issue of Developmental Cell, Conn et al. shed a novel light on the molecular mechanism of Chk1 activation and raise the possibility of a developmental checkpoint that regulates Chk1 in response to the nuclear/cytoplasmic ratio.
