James G. Morin and J.W. Hastings found that it has the same Stokes shift as related versions found in genus Obelia and Renilla.
James G. Morin and J.W. Hastings found that it has the same Stokes shift as related versions found in genus Obelia and Renilla. Its discovery by Osamu Shimomura followed up on the work of Frank Johnson. Two different variants of it are used in a FRET procedure, and it is commonly used as the probe in a FRAP assay. Its beta-barrel structure houses a highly conjugated chromaphore that is stimulated by the 470-nanometer emission of apoaequorin, the excited version of aequorin. That stimulation causes conformational changes in a serine-tyrosine-glycine sequence at its center, resulting in light emitted at 508 nanometers. It has been used to easily observe gene or protein expression because it glows its namesake color when exposed to blue light. First isolated from jellyfish of the genus Aequorea, for ten points, name this peptide often used in biological studies.
