    Protocol

    Specificity / Sensitivity

    Phospho-SMAD2 (Ser465/467) (138D4) Rabbit mAb detects endogenous levels of SMAD2 only when dually phosphorylated at serines 465 and 467, and may detect SMAD3 phosphorylated at the equivalent sites. This antibody does not cross-react with other SMAD-related proteins.

    Species Reactivity:

    Human, Mouse, Rat, Mink

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser465/467 of human SMAD2.

    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-β, Smad2 and Smad3 become phosphorylated at their carboxy-termini (Ser465/467 on Smad2; Ser423/425 on Smad3) by the receptor kinase TGF-β R1 (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.
