Smad 4 is a member of the Mothers Against Dpp (MAD)-related family of proteins. So far, eight Smads have been identified and can be divided in 3 subgroups based on their structure and functions; pathway-restricted, common mediator and inhibitory Smad. Smad 4 is the common Smad (co-Smad) (1-2). Previously identified as the tumor suppressor DPC4 (deleted in pancreatic carcinoma, locus 4), Smad 4 is functionally distinct among the Smad family, and is required for the assembly and transcriptional activation of diverse, Smad-DNA complexes (3). In contrast to the R-Smads, Smad 4 is not regulated by phosphorylation, but acts as a common mediator of TGF-ß, activin, and bone morphogenetic protein signaling responses (4). Smad 4 is frequently inactivated in pancreatic, biliary and colorectal tumors (5-6).

HEK293T cells were transfected with the pCMV6-XL5 control or pCMV-SMAD4 (SC116771) cDNA for 72 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-SMAD4 Rabbit mAb. The size markers are shown in numbers and the correct 60 kDa SMAD4 protein is indicated by an arrow.
