different combinations and concentrations of
ligands // RNAi knockdowns
42 different ligands
cytoplasm
5 different Type II receptors
7 different Type I receptors
Smad1/2
nucleus
activated Smad complex
co-activator or co-repressor
cell-specific DNA-binding cofactors
Smad1/2-responsive genes
Smad4
Assay 2 Transcriptional assay using
Smad-responsive promoter elements No temporal
