This PDF file includes:

  • Fig. S1. Itk is part of the cSMAC signaling complex.
  • Fig. S2. Itk regulates multiple elements of the spatiotemporal organization of T cell signaling.
  • Fig. S3. Centrally targeted active Cdc42 does not restore actin patterning, TCR patterning, or IL-2 secretion in Itk-deficient T cells.
  • Fig. S4. Itk regulates the recruitment of Cdc42 GEFs to the T cell–APC interface.
  • Fig. S5. SLAT knockdown results in a phenotype that resembles that of Itk deficiency.
  • Fig. S6. TCR clustering is diminished in TH2 cells and the Itk SH2 domain is required for efficient recruitment of Itk to the cSMAC.
  • Table S1. Movie descriptions.
