Figure 4From: Structural basis of regulation and substrate specificity of protein kinase CK2 deduced from the modeling of protein-protein interactionsStructural model of binding of PKCK2α (blue) and PKCK2β (brown) during autophosphorylation. The sidechains of catalytic base, Asp156, in the catalytic subunit and the phosphorylation site, Ser 2, in the PKCK2β are also shown. (Figure generated using SETOR [44])Back to article page
