Western Blotting Image 1: SMAD2 (D43B4) XP® Rabbit mAb
Western blot analysis of extracts from HeLa cells (lane 1) or SMAD2 knock-out cells (lane 2) using Smad2 (D43B4) XP® Rabbit mAb #5339 (upper), and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower). The absence of signal in the SMAD2 knock-out HeLa cells confirms specificity of the antibody for SMAD2.

Protocol

Specificity / Sensitivity

SMAD2 (D43B4) XP® Rabbit mAb detects endogenous levels of total SMAD2 protein. This antibody does not cross-react with SMAD3.

Species Reactivity:

Human, Mouse, Rat, Monkey

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of mouse SMAD2 protein.

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).
