Its bioluminescence was studied decades before the protein was isolated from the animal by Osamu Shimomura in 1962. In the animal, the protein occurs together with the green fluorescent protein to produce … See more Work on aequorin began with E. Newton Harvey in 1921. Though Harvey was unable to demonstrate a classical luciferase-luciferin reaction, he showed that water could produce light from dried photocytes and … See more Aequorin is a holoprotein composed of two distinct units, the apoprotein that is called apoaequorin, which has an approximate molecular weight of 21 kDa, and the prosthetic group coelenterazine, the luciferin. This is to say, apoaequorin is the enzyme produced … See more Since the emitted light can be easily detected with a luminometer, aequorin has become a useful tool in molecular biology for the measurement of intracellular Ca levels. The early successful purification of aequorin led to the first experiments involving the … See more • Swiss-Prot Aequorin entry Archived 2007-03-23 at the Wayback Machine See more Aequorin is presumably encoded in the genome of Aequorea. At least four copies of the gene were recovered as cDNA from the animal. Because the genome has not been sequenced, it is unclear if the cDNA variants can account for all of the isoforms of the protein. See more Early studies of the bioluminescence of Aequorea by E. Newton Harvey had noted that the bioluminescence appears as a ring around the bell, and occurs even in the absence of air. This was remarkable because most bioluminescence reactions require See more Apoaequorin is an ingredient in "Prevagen", which is marketed by Quincy Bioscience as a memory supplement.
