Description

Kemptide is a synthetic heptapeptide that acts as a specific substrate for cAMP-dependent protein kinase (PKA).

In Vitro

Kemptide is a synthetic construct of a substrate for cAMP-dependent protein kinase (PK). Different types of intact cells catalyze the phosphorylation of Kemptide in the presence of extracellular ATP and cAMP with Km values of 3-4 uM for Kemptide[1]. Kemptide is a synthetic peptide substrate derived from pyruvate kinase[2].

Kinase Assay
[2]

PKA activity is measured in pools of 10 oocytes at various stages of maturation using the SignaTECT cAMP-Dependent Protein Kinase (PKA) Assay System. Measurements of basal PKA activity are performed in the absence of exogenous cAMP, whereas measurements of total (cAMP-stimulated) PKA activity are performed in reaction buffer containing 0.025 mM cAMP[2].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
