GO:0071142

Synonyms

• SMAD1 homotrimer complex
• SMAD2 homotrimer complex
• SMAD2 protein complex
• SMAD3 homotrimer complex
• SMAD3 protein complex

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. (3)
