Western Blotting

Western blot analysis of extracts from HepG2 cells treated with TGFbeta for the indicated times, using Phospho-Smad2 (Ser465/467) Antibody (upper) or Smad2 antibody (lower).
Members of the Smad family of signal transduction molecules are components of a critical intracellular pathway that transmit TGF-β signals from the cell surface into the nucleus. Three distinct classes of Smads have been defined: the receptor-regulated Smads (R-Smads), which include Smad1, 2, 3, 5, and 8; the common-mediator Smad (co-Smad), Smad4; and the antagonistic or inhibitory Smads (I-Smads), Smad6 and 7 (1-5). Activated type I receptors associate with specific R-Smads and phosphorylate them on a conserved carboxy-terminal SSXS motif. The phosphorylated R-Smad dissociates from the receptor and forms a heteromeric complex with the co-Smad (Smad4), allowing translocation of the complex to the nucleus. Once in the nucleus, Smads can target a variety of DNA binding proteins to regulate transcriptional responses (6-8).
Following stimulation by TGF-beta, Smad2 and Smad3 become phosphorylated at their carboxyl termini by the receptor kinase (serines 465 and 467 on Smad2; serines 423 and 425 on Smad3) by TbetaR-I (9-11). Following phosphorylation, Smad2 and Smad3 form a heteromeric complex with the co-smad family member Smad4. These complexes are translocated to the nucleus where they bind DNA and regulate gene transcription.
