Alk4 S275M restores phospho-Smad2 signaling to SB-431542-treated animal caps and embryos. Embryos (Xenopus and zebrafish) were injected with 100 pg Alk4 S275M or 100 pg Alk4 WT. Western blots for phospho-Smad2 were performed on (A) stage 8.5 Xenopus animal caps treated with 100 μM SB-431542 or DMSO followed by 2 nM soluble activin protein, and (B) 50% epiboly zebrafish embryos treated with 100 μM SB-431542 at 16-cell stage. Cytoskeletal actin and tubulin were used as loading controls for panels A and B, respectively.
