CAMK2G and cardiac hypertrophy: They could also modify the expression of other ion channels, exemplified by Li et al. [81] in the calmodulin kinase II (CaMKII)-mediated modifications in Ca2+-activated K+ (SK2) channel expression under conditions of cardiac hypertrophy [93], in addition to CaMKII actions in increasing INaL (Liu et al. [51]) (figure 4e).
