SMAD4 is a class of common mediator SMAD (Co-SMAD), which belongs to the dwarfin/SMAD family. It conducts cell signals through the SMAD4/TGF-β pathway and plays an important role in promoting bone development and tissue homeostasis. SMAD4 induces chondrogenesis of human bone marrow mesenchymal stem cells, and specifically targets stem cells to participate in self-renewal of hematopoietic stem cells. SMAD4 can also protect cell apoptosis and inhibit epithelial cell proliferation, showing antitumor effects[1][2]. SMAD4 Protein, Human (His) has the 552 a.a. sequence (M1-D552), produced in E.coli with C-terminal 6*His-tag.
