Kemptide

Kemptide is a synthetic heptapeptide that acts as a specific substrate for cAMP-dependent protein kinase (PKA) as it carries the recognition and phosphorylation site of PKA. Various cultured cells can catalyze the phosphorylation of kemptide in the presence of extracellular ATP and cAMP (Kms = 3-4 µM) with plasma membranes remaining intact.Formal Name: L-leucyl-L-arginyl-L-arginyl-L-alanyl-L-seryl-L-leucyl-glycine.
