This PDF file includes:

  • Fig. S1. The pHSA-Dok-7-EGFP transgene is overexpressed in skeletal muscle.
  • Fig. S2. The number of myofibers was comparable in WT and Dok-7 Tg mice.
  • Fig. S3. AChR clusters formed only in Dok-7–/– myotubes that express Dok-7-EGFP.
  • Fig. S4. Transcripts for endogenous Dok-7 were distributed uniformly throughout the muscle at E18.5.
  • Fig. S5. The Myc epitope appropriately increased the molecular mass of phosphorylated MuSK-cyt.
  • Fig. S6. Dok-7 activated MuSK-cyt.
  • Fig. S7. MuSK was not activated by a Dok-7 deletion mutant lacking the PH domain or the Dok-family protein Dok-1.
  • Fig. S8. The pHSA-Dok-7-Myc transgene is overexpressed in skeletal muscle.
