Signal transduction: how rad53 kinase is activated

Curr Biol. 2005 Sep 20;15(18):R769-71. doi: 10.1016/j.cub.2005.08.057.

Abstract

Recent studies have elucidated the activation mechanism of the Rad53 checkpoint kinase and the role of Rad9-like adaptor proteins in mediating signal transduction from PIKK sensor kinases that detect DNA damage to the effector kinases that play a part in mending that damage.
