Prediction of JNK target phosphoacceptor sites close to a JNK-docking site.
A) Linear representation of known JNK targets ATF2, JUNB, and JUN with all potential ST/TPphosphosites shown. Those sites predicted by our PWM method to be likely JNK targets arelabeled as ‘JNK’. Literature-validated phosphosites are indicated with yellow crosses. The D-finder-predicted D-site is shown as a purple rectangle; the 100 amino acid window to either sideof the D-site is indicated by a thickened gray line. B) Linear representation of full-lengthSMTNL2 protein and all potential ST/TP phosphosites. Labeling as above. Phosphositesidentified in the mass spectrometry/mutagenesis experiments described further below areindicated with yellow crosses
