homomeric SMAD protein complex
Term Information
Accession
GO:0071142
Name
homomeric SMAD protein complex
Ontology
cellular_component
Synonyms
SMAD1 homotrimer complex, SMAD1 protein complex, SMAD2 homotrimer complex, SMAD2 protein complex, SMAD3 homotrimer complex, SMAD3 protein complex
Alternate IDs
GO:0071143
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.
