Camui detects activation of CaMKII. (A) Camui FRET changes reflect activation of CaMKII either directly through Ca2+/CaM binding or autonomously by phosphorylation or oxidation. (B) Traditional kinase assays confirm our findings with Camui. (C) Oxidative stress does not affect CFP or YFP fluorescence. (D) KN-93, but not AIP, blocks the change in FRET associated with Camui activation.
