Supplementary Figure 3: Motif analysis of phosphopeptides in selected PDTs.

Phosphopeptides were matched to predefined phosphorylation motifs that are common in kinase substrates (a) or to predicted kinase-substrate (Netphorest) groups (b). Enrichment was calculated as Log2[(k/m)/(q/t)] for (a) or as (k/m)/(q/t) for (b), where k is number of phosphosites in PDT that match the named motif/Netphorest group, m is total number of phosphosites in PDTs, q is total number of phosphosites in motif/Netphorest group, and t is total number of phosphosites. Full sets of motif/Netphorest groups in different PDTs are shown in Supplementary Dataset 4.
