Background:

Smad2 is a 58 kDa member of a family of proteins involved in cell proliferation, differentiation and development. The Smad family is divided into three subclasses: receptor-regulated Smad's, activin/TGF alpha receptor-regulated (Smad2 and 3) or BMP receptor regulated (Smad1, 5, and 8); the common partner, (Smad4) that functions via its interaction to the various Smad's; and the inhibitory Smad's, (Smad6 and Smad7). Smad2 consists of two highly conserved domains, the N terminal Mad homology (MH1) and the C-terminal Mad homology 2 (MH2) domains. The MH1 domain binds DNA and regulates nuclear import and transcription while the MH2 domain conserved among all the Smad's regulates Smad2 oligomerization and binding to cytoplasmic adaptors and transcription factors. Activated Smad2 associates with Smad4 and translocates as a complex into the nucleus, allowing its binding to DNA and transcription factors. This translocation of Smad2 (as well as Smad3) into the nucleus is a central event in TGF beta signaling. Phosphorylation of threonine 8 in the calmodulin binding region of the MH1 domain by extracellular signal regulated kinase 1(ERK 1) enhances Smad2 transcriptional activity, which is negatively regulated by calmodulin. The regulation of Smad2 phosphorylation on threonine 8 by ERK 1 and calmodulin is critical for Smad2 mediated signaling.

VALIDATION IMAGES

Formalin-fixed and paraffin embedded human gastric cancer labeled with Anti-Phospho-Smad2(Thr220)Polyclonal Antibody, Unconjugated (bs-5618R) at 1:200 followed by conjugation to the secondary antibody and DAB staining


Hela cells were fixed with 4% PFA for 10min at room temperature,permeabilized with 90% ice-cold methanol for 20 min at -20℃ and incubated in 5% BSA blocking buffer for 30 min at room temperature. Cells were then stained with Phospho-Smad2 (Thr220) Polyclonal Antibody(bs-5618RR)at 1:100 dilution in blocking buffer and incubated for 30 min at room temperature, washed twice with 2%BSA in PBS, followed by secondary antibody incubation for 40 min at room temperature. Acquisitions of 20,000 events were performed. Cells stained with primary antibody (green), and isotype control (orange).
