Fig. 2.

Motif scores of dual and constitutive splice sites. (A) Graphical representation of motif scores of constitutive 5′ (blue), 3′ (cyan), and dual (red) splice sites. (B) Similar to analysis in A, except that only constitutive splice sites with the AG|GU pattern are shown. (C) Resemblance of dual splice sites to the canonical 5′ and 3′ splice-site consensus motifs. Matrix scores were ranked and converted into quantiles according to constitutive splice sites, and different thresholds (quantile 0 to 1, in steps of 0.01) were applied to count the number of sites whose scores exceed both thresholds.
