生物活性

PKI(5-24) is a potent, competitive, and synthetic peptide inhibitor of PKA (cAMP-dependent protein kinase), with a Ki of 2.3 nM. PKI(5-24) corresponds to residues 5-24 in the naturally occurring heat-stable protein kinase inhibitor[1][2].

体外研究
(In Vitro)

PKI(5-24) is a 20-residue peptide has been synthesized that corresponds to the active site of the skeletal muscle inhibitor protein[1].
PKI(5-24) inhibits phosphotransferase activity of the mutant cGMP kinase with higher potency than that of wild type, with Ki values of 42 μΜ and 160 μΜ, respectively[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
