Its utility is the result of a modified (*) imidazolidin and antioxidants such as vitamin E derivatives can protect against photo-bleaching of this protein's chromophore.
Linking these proteins with a calmodulin binding domain spacer creates an indicator for calcium ions. It is a companion protein to aequorin and can be employed as a fusion tag for protein detection. Its utility is the result of a modified (*) imidazolidin and antioxidants such as vitamin E derivatives can protect against photo-bleaching of this protein's chromophore. For 10 points, name this protein obtained from the jellyfish Aequorea victoria that posses an internal fluorophore, which emits light at a characteristic wavelength.
