Opis

General description

A highly potent, reversible, and substrate competitive membrane-permeable peptide that selectively inhibits protein kinase G Iα (PKG Iα) (K_i = 25 nM). Inhibitor peptide is fused to the Drosophila Antennapedia homeo domain peptide to allow membrane permeability. Shown to efficiently cross the membrane of arterial smooth muscle cells and inhibit nitric oxide-induced (NO-induced) vasodilation (EC₅₀ = 47 µM). Inhibits protein kinase A (PKA) activity only at much higher concentrations (K_i = 493 µM). The carrier peptide is also available under Cat. no. 287895.
