The effect of phosphorylation of calcineurin on calmodulin (CaM) binding was examined using a synthetic peptide which contains the CaM-binding domain and the serine phosphorylation site. The peptide, corresponding to residues 391-414 of brain calcineurin A subunit, was rapidly phosphorylated by protein kinase C and Ca2+ CaM-dependent protein kinase II but not by cAMP-dependent protein kinase. Phosphorylation of peptide 391-414 did not significantly alter the binding of CaM when compared to the non-phosphorylated peptide.
