PKA Inhibitor Fragment (6-22) amide

PKA inhibitor fragment (6-22) amide is a synthetic peptide inhibitor of cAMP-dependent protein kinase (PKA, Ki = 1.7 nM) derived from the heat-stable PKA inhibitor protein PKI. It is the shortest synthetic PKI peptide that retains high potency for PKA inhibition. Both the arginine-containing pseudosubstrate site of the PKI peptide in its COOH terminus and the residue Phe10 in NH2-terminal portion are required for this high affinity binding.Formal Name: L-threonyl-L-tyrosyl-L-alanyl-L-alpha-aspartyl-L-phenylalanyl-L-isoleucyl-L-alanyl-L-serylglycyl-L-arginyl-L-threonylglycyl-L-arginyl-L-arginyl-L-asparaginyl-L-alanyl-L-isoleucinamide.
