This PDF file includes:

  • Fig. S1. Six tyrosine residues of PKM2 are phosphorylated in cells harboring active FGFR1 mutants.
  • Fig. S2. FGFR1 directly phosphorylates PKM2.
  • Fig. S3. ABL, JAK2, and FLT3 effectively and directly phosphorylate PKM2 at Y105 in vitro, whereas epidermal growth factor receptor (EGFR) is less effective.
  • Fig. S4. Presence of the PKM2 Y105F mutant in lung cancer H1299 cells leads to decreased proliferation under hypoxic conditions.
  • Fig. S5. Y105 phosphorylation may affect FBP-binding to PKM2 in an "intra-molecular manner" in cellular contexts with high tyrosine phosphorylation stoichiometry of PKM2.
  • Fig. S6. FGFR1 binds PKM2 in a tyrosine phosphorylation–dependent manner but this binding is dispensable for FGFR1-dependent inhibition of PKM2.
