"Phosphorylation of CaM at four sites by CK2 was found to follow a sequential order, with Ser81 as the first, Thr79 as the second, and Ser101 or Thr117 as the third. We found that in the complex between CaM and CaMKII, residue E115 of CaM is strongly interacting with K299 of the kinase through forming a salt-bridge (PDB entry 1WEL), it is quite likely that the phosphorylation induced structural change can disrupt this interaction and negatively affect the binding between the two proteins"
