title: Checkpoint adaptation; molecular mechanisms uncovered.
abstract: Adaptation to the DNA damage checkpoint is a phenomenon long thought to be confined to the unicellular world. A new report in this issue of Cell by suggests the presence of a checkpoint adaptation pathway in Xenopus egg extracts that displays interesting molecular parallels to adaptation in yeast.
