title: A novel effector protein modulates response regulator activity without altering phosphorylation.
abstract: Genes positively regulated by the global transcriptional response regulator CtrA are not expressed during a life cycle stage of Caulobacter crescentus when the regulator is activated by phosphorylation. Gora et al. (2010), in this issue of Molecular Cell, have discovered a novel effector protein that prevents activation but not repression by the regulator without altering its phosphorylation.
