General Information
Term homomeric SMAD protein complex ID (Ontology) GO:0071142 (Gene Ontology)
Definition 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.[ PubMed:11779505 PubMed:16322555 PubMed:9670020 ]
