pp60 (v-SRC) Autophosphorylation Site, Phosphorylated is a phosphorylated peptide derived from an EGFR substrate. It serves as a valuable tool for quantifying phosphorylated substrates in screening EGFR Kinase inhibitors.
ARQ 069 (3.8-60 μM; for 2 hours) reduces the degree of phosphorylation of FGFR (predominantly FGFR2) in a concentration-dependent manner, without decreasing β-actin. ARQ 069 shows an affinity for FGFR2 of 5.2 μM. ARQ 069 inhibits FGFR phosphorylation in K
