Direct interaction of Stat3 and the gp130-derived phosphopeptide. Baculovirus-expressed full-length Stat3 (b-ST3-FL) and the deletion mutants (b-ST3-ΔN1H and b-ST3-ΔN4H) were purified from Sf9 cells, and 0.5 μg of each protein was subjected to peptide binding with either pY3 or Y3 as described in the legend to Fig. 4 (upper panel) or Western blot analysis (lower panel).
