This PDF file includes:

  • Fig. S1. Validation of the anti–methyl-Lys and anti–methyl-Arg antibodies.
  • Fig. S2. Mass spectra of methylated VEGFR-2 peptides and their locations.
  • Fig. S3. Ratios of methylation of Lys1041 and tyrosine phosphorylation of VEGFR-2.
  • Fig. S4. Phosphorylation of Lys and Arg mutant CKRs in response to ligand stimulation.
  • Fig. S5. Mutation of Lys1041 to Phe inhibits, whereas mutation to Gln partially preserves, phosphorylation of VEGFR-2.
  • Fig. S6. The K1041R mutation does not inhibit ligand binding or dimerization of VEGFR-2.
  • Fig. S7. Adox treatment inhibits the methylation of VEGFR-2.
  • Fig. S8. Remethylation of the K1041R VEGFR-2 mutant does not increase its tyrosine phosphorylation.
