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. |

| + | Fluorescent proteins are transformative tools; thus, any brightness increase is a welcome improvement. We invented the "vGFP strategy" based on structural analysis of GFP bound to a single-domain antibody, predicting tunable dimerization, enhanced brightness (ca. 50 %), and improved pH resistance. We verified all of these predictions using biochemistry, crystallography, and single-molecule studies. We applied the vsfGFP proteins in three diverse scenarios: single-step immunofluorescence in vitro (3x brighter due to dimerization); expression in bacteria and human cells in vivo (1.5x brighter); and protein fusions showing better pH resistance in human cells in vivo. The vGFP strategy thus allows upgrading of existing applications, is applicable to other fluorescent proteins, and suggests a method for tuning dimerization of arbitrary proteins and optimizing protein properties in general. | ||
