Â It may be (*)
In 2007, Lichtman and Saines used multiple variants of this protein to map neural circuitry in a technique known as Brainbow. Â The structure of this protein consists of a beta barrel with an alpha helix running up through its central axis. Â In the center of that barrel, post-translational modification of three amino acids: serine-65, tyrosine-66, and glycine-67 form an active imidazolinone chromophore. Â It may be (*)Â fused to endogenous proteins to track their activity, or employed in techniques like FLIP, FRAP, or DNA microarrays. Â The wild-type version of this protein, found in Aequoria victoria, has two excitation peaks at 395 and 475 nanometers, and Tsien, Chalfie, and Shimamura won the Nobel prize in 2008 for their work on this substance. Â For 10 points, identify this protein isolated from jellyfish which is used as a reporter due to its characteristic colorful glow.
