KRPPKLGQIGRAKRVVIEDDRIDDVLK-OH Off-white solid. Supplied as a trifluoroacetate salt. HYGROSCOPIC. PACKAGED UNDER INERT GAS. A potent and specific inhibitor of CaMK II (IC50 = 50 nM for both the total and Ca2+-independent CaMK II activity). Exhibits inhibitory activity across converged species, including rat brain, goldfish brain, and Drosophila (IC50 range 100-400 nM). Does not affect the activities of CaMK I, CaMK IV, CaMKK, PKA, or PKC. The peptide sequence corresponds to the inhibitory domain of CaMK IIN. Purity: ≥95% by HPLC.
