Upon binding of TGF-beta to cell surface complexes of type I and type II receptor serine/threonine kinases, the type II receptor phosphorylates the type I receptor, which further phosphorylates the receptor-regulated (R-) Smads, Smad2 and Smad3 (3). Phosphorylated R-Smads oligomerize with the common mediator (Co) Smad4 and accumulate in the nucleus where they regulate gene expression.\\\"" . . "Selventa" . . . .
