CAMK2G and chronic kidney disease: A recent study discovered that protein kinase A (PKA) phosphorylated PLB‐Ser16 and CaMKII exclusively catalysed the phosphorylation of PLB‐Thr17.25 Our study demonstrated increased phosphorylation of PLB‐Thr17 protein and no change in PLB‐Ser16 phosphorylation in CKD ventricles (data not shown), which suggests higher CaMKII, not PKA, activity in CKD ventricles.
