Dun1 counts on rad53 to be turned on.
In a recent issue of Molecular Cell, Lee et al. (2008) demonstrate that the forkhead-associated (FHA) domain of Dun1, a Chk2-related kinase involved in DNA damage signaling, selectively binds a diphosphorylated motif found in its paralog and upstream regulator Rad53.
