Chemical Name: N-[3-(3,4-Dihydroxyphenyl)-1-oxo-2-propenyl]-O-phosphono-L-tyrosyl-L-α-glutamyl-L-α-glutamyl-L-isoleucyl-L-glutamic acid
Biological ActivityCaffeic acid-pYEEIE is a phosphopeptide ligand for the src SH2 domain (IC50 = 42 nM); displays 30-fold higher affinity than N-acetyl-O-phosphono-Tyr-Glu-Glu-Ile-Glu (Ac-pYEEIE, Cat. No. 1927).
(Modifications: Tyr-1 = N-[3-(3,4-Dihydroxyphenyl)-1-oxo-2-propenyl]-)-pTyr, Glu-2 = αGlu, Glu-3 = αGlu)
