GENETICALLY ENCODED FLUORESCENT SENSORS FOR DETECTING INTRACELLULAR SIGNALLING THROUGH DIACYLGLYCEROL PATHWAYS

摘要

Described herein are novel fluorescent sensors for Diacyl Glycerol (DAG) and hosphatidylinositol 4,5-bisphosphate (PIP2) that are based on circularly permuted fluorescent proteins. These sensors use less visible spectrum than FRET-based sensors, produce robust changes in fluorescence, and can be combined with one another, or with other sensors, in amultiplex assay on standard fluorescent plate readers or live cell imaging systems.
