All mammalian R-Smads and Smad4 reside in the cytoplasm
Phosphorylated R-Smads quickly form complexes with Smad4 and possibly prior to nuclear translocation

Nuclear translocation of R-Smads is independent of Smad4
Whereas translocation of Smad4 after TGFB siglaing seems to require the presence of an activated R-Smad
