Large-scale discovery of ERK2 substrates identifies ERK-mediated transcriptional regulation by ETV3.

abstract：:Cyclic-di-GMP (c-di-GMP) is a bacterial second messenger that transduces internal and external signals and regulates bacterial motility and biofilm formation. Some organisms encode more than 100 c-di-GMP-modulating enzymes, but only for a few has a signal been defined that modulates their activity. We developed and ap...
