Striatal DARPP32-Thr34 phosphorylation is enhanced in RGS9-deficient mice.

<p>(<b>a</b>) Total DARPP32 from striatal homogenates of 3-month-old wt and RGS9-deficient mice was measured by Western blot quantification and normalized to actin. (<b>b</b>) DARPP32 phosphorylation at Thr34 and Thr75 is given relative to total DARPP32. Representative Western blots are shown, quantification was performed with n = 6–8 per genotype.
