def: "A protein complex composed of a single type of SMAD family proteins. In the absence of Smad4, phosphorylation of R-SMADs results in their homotrimerization. However, these complexes do not appear to import into the nucleus and are assumed to be transcriptionally inactive." [GOC:bhm, GOC:mah, PMID:11779505, PMID:16322555, PMID:9670020]
