PKI (5-24), PKA Inhibitor is a potent, competitive, synthetic peptide inhibitor of PKA (cAMP-dependent protein kinase) derived from the active domain of the naturally-occurring heat-stable inhibitor protein PKI. This pseudosubstrate inhibitor peptide mimics the protein substrate by binding to the catalytic site via the arginine-cluster basic subsite, which provides high specificity. PKA catalytic subunit residues Tyr235 and Phe239 form a sandwich-like structure with residue Phe10 of PKI (5-24), PKA Inhibitor this is a prominent enzyme-substrate interaction site. PKI (5-24), PKA Inhibitor exhibits a Ki of 2.3 nM with respect to PKA and is an extremely weak inhibitor of cGMP-dependent protein kinase (PKG).
