title: Real-time fluorescence monitoring of GSK3beta-catalyzed phosphoryation by use of a BODIPY-based Zn(II)-Dpa chemosensor.
abstract: We developed a new fluorescence assay system for GSK3beta-catalyzed kinase reaction using the BODIPY-based fluorescent chemosensor. This system exploits the selective sensing property of the chemosensor for a (i, i+4) bis-phosphorylated peptide, which allows us to conveniently detect the phosphorylation reaction with a fluorescence increase in a real-time fashion.
