ANTI-SMAD4 antibody produced in mouse
SIGMA/SAB1412182 - clone 3D7, purified immunoglobulin, buffered aqueous solution
Synonym: DPC4; JIP; MADH4; SMAD4
Product Type: Chemical
Proximity Ligation Assay Proximity Ligation Analysis of protein-protein interactions between AKT1 and SMAD4. Huh7 cells were stained with anti-AKT1 rabbit purified polyclonal 1:1200 and anti-SMAD4 mouse monoclonal antibody 1:50. Each red dot represents the detection of protein-protein interaction complex, and nuclei were counterstained with DAPI (blue).
Western Blotting QC Western Blot detection against Immunogen (37.84 kDa).
ELISA Detection limit for recombinant GST tagged SMAD4 is approximately 3 ng/mL as a capture antibody.

| Biochem/physiol Actions: | Upon TGFβ (transforming growth factor β) activation, SMAD (mothers against decapentaplegic homolog) proteins are responsible for transcription activation in the nucleus. SMAD4 is a crucial protein of TGFβ signaling. It promotes association of SMAD2/4 to DNA and helps SMAD1/2 in transcription stimulation. Mutations in SMAD4 are linked with juvenile polyposis syndrome, hereditary haemorrhagic telangiectasia and Myhre syndrome. In renal cell carcinoma, it activates forkhead box protein H1 and thereby inhibits the progression of the carcinoma. SMAD4 is considered as a tumor suppressor protein. |
