Energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca(2+)-activated photoprotein aequorin.
Post-translational modification
Contains a chromophore consisting of modified amino acid residues. The chromophore is formed by autocatalytic backbone condensation between Ser-65 and Gly-67, and oxidation of Tyr-66 to didehydrotyrosine. Maturation of the chromophore requires nothing other than molecular oxygen.
Green fluorescent protein has been engineered to produce a vast number of variously colored mutants, fusion proteins, and biosensors. 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). Further generation of mutants led to more stable proteins (at 37 degrees Celsius for example) with brighter fluorescence and longer fluorescence lifetimes. Fluorescent proteins and their mutated allelic forms have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions (PubMed:17685514, PubMed:17685554, PubMed:8578587, PubMed:8707053, PubMed:9145105, PubMed:9154981, PubMed:9759496, PubMed:9782051). Can also be used as a molecular thermometer, allowing accurate temperature measurements in fluids. The measurement process relies on the detection of the blinking of GFP using fluorescence correlation spectroscopy (PubMed:17685514).

Immunofluorescent analysis of transfected HEK293 cells with a GFP fusion protein construct, in green, and stained with chicken pAb to GFP, 5053, dilution 1:1,000, in red. The blue is DAPI staining of nuclear DNA. The 5053 antibody reveals GFP protein expressed only in transfected cells, and as a result these cells appear golden yellow in color.

Western blot analysis of HEK293 cell lysates using goat pAb to GFP, 5053, dilution 1:1,000, in green: [1] protein standard, [2] non-transfected control cells, [3] cells transfected with a GFP construct and [4] cells transfected with an mCherry construct. Strong band at ~27kDa corresponds to GFP protein detected only in cells transfected with GFP construct. This antibody does not recognize the mCherry protein. The blot was simultaneously probed with chicken pAb to HSP60, 5053, dilution 1:10,000, in red. The single band at 60kDa represents HSP60 protein expressed in all preparations.
