Immunohistochemistry analysis of SMAD2 showing staining in the cytoplasm and nucleus of paraffin-embedded human placenta tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Anti- SMAD2 Monoclonal Antibody (436500) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

SMAD2, also known as MADH2 or MAD2 regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. Smad2 interacts with the TGF-beta receptors through its interaction with the SMAD anchor for receptor activation 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 signalregulated kinase 1 (ERK1) enhances Smad2 transcriptional activity, which is negatively regulated by calmodulin.
