abstract：:Our aim was to visualize the dynamic features of Ca2+/calmodulin-dependent protein kinase II (CaMKII) activity. In order to do so, we synthesized a new reagent by conjugating a fluoroprobe, 6-acryloyl-2-dimethylaminonaphthalene (acrylodan), to syntide 2, a specific peptide substrate for CaMKII. In cell-free conditions...
