CaMKII belongs to the subfamily of multifunctional Ser/Thr kinases, which phosphorylate various substrates and regulate numerous cellular functions (Soderling, 1999; Fujisawa, 2001; Hook and Means, 2001; Rusciano et al., 2012) intimately involved in heart diseases (Braun and Schulman, 1995; Erickson et al., 2008; Anderson et al., 2011). Here, CAMK2G is linked to heart disorder.
