    Protocol

    Specificity / Sensitivity

    Phospho-Smad2 (Ser465/467) Antibody detects endogenous levels of Smad2 only when dually phosphorylated at Ser465 and Ser467, and may detect phosphorylated Smad3 at its equivalent site. This antibody does not cross-react with other Smad-related proteins.

    Species Reactivity:

    Human, Mouse, Rat

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Chicken, Xenopus, Zebrafish

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser465/467 of human Smad2. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Members of the SMAD family of signal transduction molecules are components of a critical intracellular pathway that transmit TGF-β signals from the cell surface into the nucleus. Three distinct classes of SMADs have been defined: the receptor-regulated SMADs (R-SMADs), which include SMAD1, 2, 3, 5, and 9; the common-mediator SMAD (co-SMAD), SMAD4; and the antagonistic or inhibitory SMADs (I-SMADs), SMAD6 and 7 (1-5). Activated type I receptors associate with specific R-SMADs and phosphorylate them on a conserved carboxy-terminal SSXS motif. The phosphorylated R-SMADs dissociate from the receptor and form a heteromeric complex with SMAD4, initiating translocation of the heteromeric SMAD complex to the nucleus. Once in the nucleus, SMADs recruit a variety of DNA binding proteins that function to regulate transcriptional activity (6-8).

    Following stimulation by TGF-beta, Smad2 and Smad3 become phosphorylated at their carboxyl termini by the receptor kinase (serines 465 and 467 on Smad2; serines 423 and 425 on Smad3) by TbetaR-I (9-11). Following phosphorylation, Smad2 and Smad3 form a heteromeric complex with the co-smad family member Smad4. These complexes are translocated to the nucleus where they bind DNA and regulate gene transcription.
