title: BRCTing up is hard to do.
abstract: In this issue of Molecular Cell, Usui et al. (2009) show that Mec1-phosphorylated Rad9 SCD interacts with the BRCT domain, promoting oligomerization. This sustains the DNA damage checkpoint and is suppressed by Rad53 phosphorylation in a negative feedback circuit.
