WebbIn addition, by binding to tyrosine phosphorylated PDGFR or IRS1, PI-3 kinase is translocated to the cell membrane where its substrate PtdIns(4,5)P 2 is found. Activation by Tyrosine Phosphorylation. It has been shown that tyrosine phosphorylation of certain target proteins is required for ligand stimulation of their enzymatic activity . In ... Webbthe side chain of tyrosine $-CH_2\mbox-Ph\mbox-{\scriptsize (p)}OH$ is an even weaker acid $[R\mbox-OH \rightleftharpoons R\mbox-O^- + H^+]$ so the IEP is 5.66; And every amino acid has more or less contribution to the IEP of a protein.
