Western blot for the Pka downstream target VASP. Phosphorylation of VASP at Serine 157, the primary Pka directed site, is detected at the 50 kDa band. Unphosphorylated VASP is detected at the 46 kDa band. Beta-actin served as the loading control. Densitometry of VASP phosphorylated at Ser157 normalized to unphosphorylated VASP is quantified for n = 8 per group. * P < 0.05 vs. WT.
