This PDF file includes:

  • Supplementary Text
  • Fig. S1. Amino acid sequence alignment of TAK1 from various species.
  • Fig. S2. IL-1 induces Lys63-linked polyubiquitination of TAK1 KR mutants.
  • Fig. S3. The K209R mutation of TAK1 does not affect the interaction between TAK1 and TAB2.
  • Fig. S4. Analysis of the association between TAK1, TRAF6, and MEKK3 in transiently transfected cells.
  • Fig. S5. The activation of TAK1 by TAB1 does not require MEKK3 or the Lys63-linked polyubiquitination of TAK1.
  • Fig. S6. The K209R mutation of TAK1 does not abolish the intrinsic kinase activity of TAK1.
  • Fig. S7. Possible involvement of UbcH7 in TRAF6-induced activation of NF-κB.
  • Fig. S8. Effect of a partial reduction in the abundance of Ubc13 on IL-1 signaling.
  • Fig. S9. RING domain–independent and zinc finger–dependent activation of NF-κB by IL-1.
  • Fig. S10. MEKK3, but not TAK1, is required for the Zinc pathway.
  • Fig. S11. Severe reduction in the IL-1–induced activation of NF-κB in the absence of MEKK3.
  • Fig. S12. The T6mZ5 mutant, in which the fifth zinc finger is inactivated, activates the RING pathway but not the Zinc pathway.
  • Fig. S13. Time-dependent activation of NF-κB in Tak1–/– MEFs.
  • Fig. S14. Time-dependent phosphorylation of IκBα induced by RING domain–defective mutants of TRAF6.
  • Fig. S15. Cooperation of the RING and Zinc pathways results in the prolonged activation of NF-κB in the nucleus.
  • Fig. S16. IL-1–induced polyubiquitination of MEKK3 depends on the RING domain of TRAF6 and Ubc13.
  • Fig. S17. MEKK3 associates with p62 in a PB1 domain–dependent manner.
