Polyubiquitylation leading to proteasomal degradation is a well-established mechanism for regulating TGF-β signal transduction components such as receptors and Smads. Recently, an equally important role was suggested for monoubiquitylation of both Smad4 and Receptor-associated Smads that regulates their function without protein degradation. Monoubiquitylation of Smads was discovered following the identification of deubiquitylases required for TGF-β signaling, suggesting that continuous cycles of Smad mono- and deubiquitylation are required for proper TGF-β signal transduction. Here we summarize and discuss recent work on Smad mono- and deubiquitylation.
