Figure 2From: Structural basis of regulation and substrate specificity of protein kinase CK2 deduced from the modeling of protein-protein interactionsModel of calmodulin (orange) binding to PKCK2α (purple) The catalytic base (Asp 156) is shown as red sphere, site of phosphorylation (Ser 81) is shown in green. The site of phosphorylation is in central helix of the calmodulin. Figure generated using SETOR [44].Back to article page
