SMAD4 is a member of the Mothers Against Dpp (MAD)-related family of proteins. SMAD4 is functionally distinct among the SMAD family, and is required for the assembly and transcriptional activation of diverse, SMAD-DNA complexes. SMAD4 appears to be not regulated by phosphorylation, but acts as a common mediator of TGF-beta, activin, and bone morphogenetic protein signaling responses. SMAD4 is frequently inactivated in pancreatic, biliary and colorectal tumors.
