This is a myristoylated form of Autocamtide-2-Related Inhibitory Peptide (AIP), a highly potent and specific substrate competitive inhibitor of Calmodulin-Dependent Protein Kinase ll (CaMKII). AIP is derived from Autocamtide-2, a substrate for CaMKII, with the Thr-9 phosphorylation site substituted with Ala.
