This PDF file includes:

  • Fig. S1. Persistent degradation of Act1 is mediated by continuous stimulation with IL-17.
  • Fig. S2. IL-17 stimulates Act1 degradation through a ubiquitin-dependent proteasomal pathway.
  • Fig. S3. Stimulation with IL-17 may lead to Act1 degradation in vivo.
  • Fig. S4. The kinase responsible for Act1 phosphorylation remains unknown.
  • Fig. S5. Stimulation with either BAFF or CD40L does not lead to the phosphorylation and degradation of Act1.
  • Fig. S6. Overexpression of the ΔF-box mutant TrCP1 enables TNF-α–stimulated accumulation of pIκBα.
  • Fig. S7. The abundance of Act1 protein correlates with the strength of the IL-17– dependent response.
  • Fig. S8. Proposed model for the intrinsic mechanisms that control the IL-17 signaling pathway.
