Training Set (.xls, 341K)

Variable Loadings on PCs from the PCA for Thr, Tyr, Ser (.xls, 83Mb)

Supplementary Figures 1&2 (.doc, 229K)

Supplementary Figure 1. Histogram of pairwise sequence comparisons of the 704 protein sequences used in this study. The dataset consisted of highly non-redundant protein sequences as evidenced by the low levels of sequence identities.
Supplementary Figure 2. Comparison of Receiver Operator Characteristics (ROCs) for Phos3D and other commonly used phosphorylation site prediction programs applied to serine, threonine, and tyrosine sites as well as selected kinase-specific sites as indicated in the respective legends.
