Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca(2+)-activated photoprotein aequorin. Publication Abstract from PubMed Expanding the genetic code opens new avenues to modulate protein function in real time. By genetically incorporating photoreactive phenyl azide, the fluorescent properties of green fluorescent protein (GFP) can be modulated by light. Depending on the residue in GFP programmed to incorporate the phenyl azide, different effects on function and photochemical pathways are observed.
