It is commonly used as a reporter gene by fusing it to the gene of interest, which allows one to localize the fusion protein.
Replacing residues 147 and 204 of this protein with cysteine makes it an effective sensor of a compartment's glutathione redox potential. This molecule contains a posttranslationally-formed bond between glycine-67 and serine-65 to form a five-membered ring with tyrosine-66. That structure is located inside this molecule's beta-barrel, which protects the central feature from water. It is commonly used as a reporter gene by fusing it to the gene of interest, which allows one to localize the fusion protein. Osamu Shimomura isolated it from Aequorea victoria, a jellyfish. For 10 points, name this protein often used in biological research that emits a certain color light when excited.
