Abstract

Green Fluorescent Protein (GFP) and other related fluorescent proteins are generally used as genetically encoded, chemically inert labels in vivo. This review focuses on the emerging application of fluorescent proteins as light-inducible intracellular photochemical partners. The first example of a chemically active GFP-like protein was the phototoxic red fluorescent protein KillerRed, which can be used for precise light-induced killing of cells, protein inactivation, and studying reactive oxygen species signaling in different cellular compartments. Moreover, recent studies revealed that various GFPs can act as light-induced electron donors in photochemical reactions with biologically relevant electron acceptors. These findings have important implications for practical uses of fluorescent proteins as well as for our understanding of the evolution and biology of this protein family.
