Figure 2

ROC curves with various features. The figure shows number of true matches (phosphorylation peptides) according to number of false matches (non-phosphorylation peptides) up to 1000 false matches among 48 kinase families. In figure, values in brackets represent number of windowed residues in peptides. From the figure we note that S _combined with S _profile (41 windowed residues) shows best performance. The fact remarks that considering long-range region is effective to identify phosphorylation peptides.
