Ubiquitinated SMAD3 is active. 1 / 1
1 |

"Here, we show that smad3 activated by tgf-beta is degraded by the ubiquitin-proteasome pathway. Smad3 interacts with a ring finger protein, roc1, through its c-terminal mh2 domain in a ligand-dependent manner. An e3 ubiquitin ligase complex roc1-scf(fbw1a) consisting of roc1, skp1, cullin1, and fbw1a (also termed betatrcp1) induces ubiquitination of smad3."
