Figure 3.

Sequences proximal to the RGD motif. (A) Select characteristic sequences for two manifestations of the motif spanning upstream of the canonical RGD domain. The upper block represents Aves and the subgroup of Reptilia that harbor two adjacent RGD sequences. The lower block represents all others. Preserved stretches of amino acids are highlighted with colored background, such that matching motifs are shaded by identical background color. (B) The common sequence motifs derived from the two groups of patterns are shown.
