Upon binding Activin A (INHBA:INHBA), Activin AB (INHBA:INHBB), or Activin B (INHBB:INHBB), the type II component of the activin receptor (ACVR2A or ACVR2B) phosphorylates the type I component ACVR1B (ALK4) at multiple serine and threonine residues within the GS domain (Attisano et al. 1996, Willis et al. 1996, Willis and Mathews 1997, Zhou et al. 2000).
