  • FunctionReceptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD2/SMAD4 complex, activates transcription. May act as a tumor suppressor in colorectal carcinoma.
  • Tissue specificityExpressed at high levels in skeletal muscle, heart and placenta.
  • Sequence similaritiesBelongs to the dwarfin/SMAD family.
    Contains 1 MH1 (MAD homology 1) domain.
    Contains 1 MH2 (MAD homology 2) domain.
  • Post-translational
    Phosphorylated on one or several of Thr-220, Ser-245, Ser-250, and Ser-255. In response to TGF-beta, phosphorylated on Ser-465/467 by TGF-beta and activin type 1 receptor kinases. Able to interact with SMURF2 when phosphorylated on Ser-465/467, recruiting other proteins, such as SNON, for degradation. In response to decorin, the naturally occurring inhibitor of TGF-beta signaling, phosphorylated on Ser-240 by CaMK2. Phosphorylated by MAPK3 upon EGF stimulation; which increases transcriptional activity and stability, and is blocked by calmodulin.
    In response to TGF-beta, ubiquitinated by NEDD4L; which promotes its degradation.
    Acetylated on Lys-19 by coactivators in response to TGF-beta signaling, which increases transcriptional activity. Isoform short: Acetylation increases DNA binding activity in vitro and enhances its association with target promoters in vivo. Acetylation in the nucleus by EP300 is enhanced by TGF-beta.
  • Cellular localizationCytoplasm. Nucleus. Cytoplasmic and nuclear in the absence of TGF-beta. On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4. On dephosphorylation by phosphatase PPM1A, released from the SMAD2/SMAD4 complex, and exported out of the nucleus by interaction with RANBP1.

I can confirm that PMA is indeed Phorbol 12-myristate 13-acetate and it was used to induce the modification of Phospho-Smad2 at S467 site.

I am sorry to hear that this product has not been performing as stated on the datasheet and for the inconvenience that this has caused. This product is highly modified post translationally. Have you performed these blots under reducing conditions? T...
