CFP/YFP SPP fusion proteins are active in a cell based SPP reporter assay. SPP fluorescent fusion expression plasmid or vector control was transfected into HEK 293T cells as described previously [19]. Activity is obtained by measuring the firefly luciferase activity and dividing it by the Renilla luciferase activity (transfection control). Activity of each SPP fluorescent fusion protein is plotted as % of endogenous activity. All four different SPP fluorescent fusion protein constructs significantly increase SPP reporter assay activity 5–8 fold above endogenous SPP activity. *p < 0.05
