We also analysed the phosphoproteomic dataset from Eμ-Myc Rel−/− lymphomas for evidence of any general changes in ATR, Ataxia Telangiectasia Mutated (ATM) or DNA-Dependent Protein Kinase (DNA-PK, PRKDC) dependent phosphorylation, whose target phosphosites generally contain an SQ or TQ motif [43]. This evidence concerns the gene ATR and lymphoma.
