  • Table S1. Statistical differences between samples 25 s after treatment with thrombin.
  • Table S2. Statistical differences between samples 25 s after treatment with PAR1 agonist.
  • Fig. S1. Gαi2 promotes phosphorylation of ERK1/2 through Tpl2.
  • Fig. S2. Phosphorylation and activation of classical and novel PKCs by thrombin depends on Tpl2.
  • Fig. S3. The phosphorylation of classical PKCs after thrombin stimulation depends on Gαi2.
  • Fig. S4. PKC inhibition attenuates thrombin-induced ERK1/2 phosphorylation but not Ca2+ signals.
  • Fig. S5. Expression profile of PLCβ isoforms in Rec-WT and Rec-EV cells.
  • Fig. S6. Thrombin-induced PLCβ3 phosphorylation at Ser537 depends on Tpl2.
  • Fig. S7. Specificity of the antibody that recognizes PLCβ3 phosphorylated at Ser537.
  • Fig. S8. The knockdown of Gβ1, Gβ2, or Gβ3, singly or in combination, interferes only partially with thrombin-induced ERK phosphorylation and Ca2+ signals.
  • Fig. S9. Number of cells before and after thrombin stimulation.
  • Fig. S10. ERK and JNK phosphorylation by S1P in immortalized MEFs and BMDMs is Tpl2-dependent.
  • Fig. S11. The increase in cytoplasmic Ca2+, induced by Wnt5a and IL-1β, but not TNF-α, depends on Tpl2.
