Effect of Ets and GATA binding site mutations on <i>ckβ</i> promoter activity.

<p>Ets and GATA binding sites are indicated with a circle and square, respectively. Mutated sites are indicated with closed circles and squares. The mutations introduced into the binding sites (underlined) are in lowercase. Each bar represents the mean ±SEM from three independent experiments performed in triplicate [***<i>p</i><0.001 vs. pGL4.10-<i>ckβ</i>(−2000/−1)].
