Abstract:
The synthesis of a fluorogenic substrate for mammalian phosphoinositide-specific phospholipase C is described. The substrate, based on the widely used fluorescein molecule, is a water-soluble substrate analog of phosphatidylinositol-4-phosphate. The fluorogenic substrate 2 is shown to be a sensitive substrate for human PI-PLC-delta1 in a continuous assay.
