Description

General description

SMAD2 or Mothers against decapentaplegic homolog 2 is a polypeptide that, as its name describes, is a homolog of the Drosophila gene: "Mothers against decepentaplegic". It belongs to the SMAD family of proteins, which belong to the TGFbeta superfamily of modulators. Like many other TGFβ family members SMAD2 is involved in cell signalling. SMAD2 modulates signals of activin and TGFbeta′s. It interacts with SMAD anchor for receptor activation (SARA). The binding of ligands causes the phosphorylation of the SMAD2 protein and the dissociation from SARA and the association with SMAD4. It is subsequently transferred to the nucleus where it forms complexes with other proteins and acts as a transcription factor. SMAD2 is a receptor regulated SMAD (R-SMAD) and is activated by bone morphogenetic protein type 1 receptor kinase.

Specificity

Recognizes human Smad2 Mr 55-60 kDa and Smad3 Mr 50 kDa as determined by using Smad2 and Smad3 transfected Cos cells.

Immunogen

Fusion protein corresponding to amino acids 186-273 of human Smad2.

Physical form

ImmunoAffinity Purified

Purified rabbit polyclonal IgG in buffer containing 0.07 M Tris-glycine, pH 7.4, 0.105 M NaCl, 0.035% sodium azide and 30% glycerol.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

Analysis Note

Control
HepG2 cell lysate.
