Immunofluorescence analysis of Phospho-SMAD2 pSer465 / pSer467 Antibody was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were treated with TGF-beta1(20ng/mL) for 15 minutes and labelled with Phospho-SMAD2 pSer465 / pSer467 Antibody(44244G) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa flour 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing Nuclear localization. Panel e showing merged image of untreated cells with less nuclear signals Panel f is a no primary antibody control. The images were captured at 40X magnification.

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.
