TSAd interactions with VEGFR2 and Src. (A) Immobilized peptides corresponding to tyrosine phosphorylation sites in VEGFR2 and TSAd were probed using TSAd GST-SH2 (left) or c-Src GST-SH2 (right) domain fusion proteins. The phosphotyrosine position in VEGFR2 or TSAd is indicated to the left and the peptide sequence to the right in the figure. The figure shows representative results from three independent experiments. Line indicates the splice of two parts of the same filter aligned to one strip. (B) Immobilized peptides corresponding to proline-rich stretches in TSAd were probed with c-Src GST-SH3 domain fusion protein. Peptide sequences are shown to the right. The figure shows representative results from three independent experiments. Line indicates the splice of two parts of the same filter aligned to one strip. (C) Schematic representation of VEGFR2, TSAd, and c-Src molecular interactions.
