Calmodulin Kinase II Inhibitor (281-309) [CaMKII(281-309)] is a peptide fragment containing the calmodulin binding site (290-309) and the phosphorylation site (Thr286). CaMKII(281-309). It is useful as a calmodulin binding peptide and can act as an inhibitor of CaM kinase II (IC₅₀ = 80 nM) by blocking Ca²⁺/calmodulin activation and enzyme active site. Alternative name: Calmodulin Dependent Protein Kinase II (281-309)
