This PDF file includes:

  • Fig. S1. Exogenous short-chain PI5P induces activation of EGFR and protects EGFR from degradation.
  • Fig. S2. Quantification of immunofluorescence and Western blots corresponding to Fig. 1.
  • Fig. S3. Phosphoinositide concentrations in HeLa cells expressing EGFP, EGFP-IpgD-WT, or EGFP-Inp54p.
  • Fig. S4. Characterization of the Tet-Off IpgD-WT HeLa stable cell line.
  • Fig. S5. PI5P production activates EGFR in the absence of detectable ligand.
  • Fig. S6. Quantification of Western blots corresponding to Fig. 2F.
  • Fig. S7. Cholesterol depletion attenuates IpgD-induced Akt activation.
  • Fig. S8. Quantification of Western blots corresponding to Fig. 3A.
  • Fig. S9. Transformation of PI(4,5)P2 into PI5P, but not into PI4P, changes EGFR localization.
  • Fig. S10. PI5P production localizes EGFR to SNX1-positive early endosomes and prevents its routing to lysosomes.
  • Fig. S11. PI5P production does not affect retrograde transport.
