Figure 4: Distribution curves of select known phosphotyrosine (A-C) and phosphoserine/threonine (D-F) motifs. The X in red represents the relative risk for the motifs and the area under the curve to the left of X represents the number of permuted sequences with relative risk lesser than the motif under study. The phosphorylated residues are shown in red (pY) or blue (pS/pT).
