Description

General description

A highly specific, potent, cell-permeable calmodulin-dependent protein kinase II (CaMKII) inhibitory peptide that contains the Antennapedia transport peptide sequence fused to the N-terminus of autocamtide inhibitory peptide-II (AIP-II) (Cat. No. 189484). AIP-II is an AIP analog where Ala³ and Val¹⁰ are replaced by Lys and Phe residues. AIP-II is reported to be more potent than CaMK-(281-302/Ala²⁸⁶) and KN-93 (Cat. No. 422708). Inhibits by binding to the autophosphorylation site, which is distinct from the exogenous substrate-binding site.
