Monoclonal Rabbit Supernatant B IP IH IC
Smad proteins belong to a group of intracellular signal transducers and downstream effectors of TGF-beta/BMP Signaling. The family consists of nine members that are highly conserved in the N- and C-terminal regions (1). Smad3 is a key component in intracellular signaling of transforming growth factor beta (TGF-beta), an inhibitor for tumor cell proliferation (2). Smad3 is activated by activin/TGF-beta receptors, which form a heteromeric complex with Smad4, translocating to the nucleus and regulating the expression of TGF-beta target genes. Interaction of Smad3 with Akt, can initiate TGF-beta induced apoptosis and cell cycle arrest (3). Smad3 expression may be critical in tumor suppression in early stages of gastric carcinogenesis (4).
