CAMK2G and Ventricular arrhythmia: In both mouse ventricular tissue (Fig. 3A–C) and corresponding isolated ventricular cardiomyocytes (Supplementary Fig. S5), Ang II treatment increased PKA and pS2808 expression in WT mice, and this increase was correlated with inducible ventricular arrhythmia, although CaMKII and pS2814 levels were unaltered.
