Influence of phosphorylation by CK2 on the thermodynamics of Hsp90β-p50Cdc37 complex formation. (A) ITC experiments of the Hsp90β-p50Cdc37 complex formation using unphosphorylated and phosphorylated proteins. The last two graphs show the interactions of Hsp90 without the acidic loop (ΔHsp90) and of the N-terminal domain (N-Hsp90). (B) Thermodynamic signatures of the protein-protein interactions.
