WebbDifferential Ubiquitination Defines the Functional Status of the Tumor Suppressor Smad4 * ... Mono- or oligo-ubiquitinated Smad4 exhibited enhanced ability to oligomerize with R-Smads, whereas mutagenesis of lysine 507 led to inefficient Smad4/R-Smad hetero-oligomerization and defective transcriptional activity. WebbSmad4 mutations have been reported in HCC. Smad4 at the genetic level is associated with loss of mRNA transcripts and subsequent loss of protein expression. Smad4 protein overexpression is present in a subset of HCC and is strongly correlated with immunostaining of the transforming growth factor beta (TGF-β).
