Green fluorescent protein can be mutated to emit at different wavelengths such as blue for BFP (when Tyr-66 is replaced by His), cyan for CFP (when Tyr-66 is replaced by Trp), and yellow for YFP (when Thr-203 is replaced by Tyr).

The green fluorescent protein (GFP) from the Pacific Northwest jellyfish Aequorea victoria has generated intense interest as a marker for gene expression and localization of gene products. The chromophore, resulting from the spontaneous cyclization and oxidation of the sequence -Ser65 (or Thr65)-Tyr66-Gly67-, requires the native protein fold ...

GFP is a ~27 kDa protein consisting of 238 amino acids derived from the crystal jellyfish Aequorea victoria. It has a fluorescent emission wavelength in the green portion of the visible spectrum (hence the name), which is due to a chromophore formed from a maturation reaction of three specific amino acids at the center of the protein (Ser65 ...

Many cnidarians utilize green-fluorescent proteins (GFPs) as energy-transfer acceptors in bioluminescence. GFPs fluoresce in vivo upon receiving energy from either a luciferase-oxyluciferin excited-state complex or a Ca 2+ -activated photoprotein.

There are several mutant GFP genes that encode mutant proteins with small differences in their nucleotide and amino acid sequences. This bioinformatics activity was designed for an upper level course in molecular biology.

GFP is a ready-made fluorescent protein, so it is particularly easy to use. Most proteins that deal with light use exotic molecules to capture and release photons. For instance, the opsins in our eyes use retinol to sense light (see the Molecule of the Month on bacteriorhodopsin).

GFP has become well established as a marker of gene expression and protein targeting in intact cells and organisms. Mutagenesis and engineering of GFP into chimeric proteins are opening new vistas in physiological indicators, biosensors, and photochemical memories. CONTENTS.

EGFP is a basic (constitutively fluorescent) green fluorescent protein published in 1996, derived from Aequorea victoria. It is reported to be a rapidly-maturing weak dimer with moderate acid sensitivity.
