Immunofluorescence analysis of SMAD3 [pSpS423/425] was done on 70% confluent log phase HeLa cells treated with TGF-beta (20ng/mL for 15 min) 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 labeled with SMAD3 [pSpS423/425] Rabbit polyclonal Antibody (44246G) at 2µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing nuclear translocation of SMAD3 [pSpS423/425]. Panel e cytoplasmic localization. Panel f shows no primary antibody control. The images were captured at 20X magnification.

The protein encoded by this gene belongs to the SMAD, a family of proteins similar to the gene products of the Drosophila gene 'mothers against decapentaplegic' (Mad) and the C. elegans gene Sma. SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways. This protein functions as a transcriptional modulator activated by transforming growth factor-beta and is thought to play a role in the regulation of carcinogenesis.
