Abstract:
:Intracellular reactions on nonenzymatic proteins that activate cellular signals are rarely found. We report one example here that a designed peptide derivative undergoes a nucleophilic reaction specifically with a cytosolic PDZ protein inside cells. This reaction led to the activation of ephrin-B reverse signaling, which subsequently inhibited SDF-1 induced neuronal chemotaxis of human neuroblastoma cells and mouse cerebellar granule neurons. Our work provides direct evidence that PDZ-RGS3 bridges ephrin-B reverse signaling and SDF-1 induced G protein signaling for the first time.
