The activated TGF-beta receptor complex is internalized by clathrin-mediated endocytosis into early endosomes. SARA resides in the membrane of early endosomes. Crystallographic studies suggest that dimeric SARA in the early endosome coordinates two R-SMAD molecules (SMAD2 and/or SMAD3) per one receptor complex.
