The functional Ets binding site was found to bind Ets family proteins , principally GA-binding protein and Elf-1 and could be transactivated by GABPalpha and -beta synergistically.
 protein: GABPalpha; protein: GA-binding protein; protein: Elf-1; protein: Ets family proteins; protein: -beta; DNA: Ets binding site
