Figure 3

The predicted key binding amino acids of the triple loop structures from the α4 and β1 subunits. The amino acids with the highest predicted binding affinities to the EDA-FN peptide (grey) are highlighted within (A) the α4 subunit triple loop finger-like domains of the integrin receptor cleft (blue), and (B) the β1 subunit triple loop finger-like domains of the integrin receptor cleft (red). The β1 subunit was used for visualization.
