Gdf11 signals through both activin type IIA (ActRIIA) and type IIB (ActRIIB) receptors to pattern axial vertebrae; biochemical studies showed Gdf11 binds both receptors and induces phosphorylation of Smad2. Genetic studies demonstrated ActRIIA and ActRIIB cooperatively mediate Gdf11 signaling, and each can compensate for the other. |
