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.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nhMAD-2; hSMAD2; JV18; JV18-1; MAD homolog 2; Mad protein homolog; Mad-related protein 2; MAD, mothers against decapentaplegic homolog 2; MADH2; MADR2; MGC22139; MGC34440; mother against DPP homolog 2; Mothers against decapentaplegic homolog 2; Mothers against DPP homolog 2; Sma- and Mad-related protein 2; SMAD 2; SMAD family member 2; SMAD, mothers against DPP homolog 2; SMAD2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mi\nSENSITIVITY: Endogenous\nMW (kDa): 60\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798070972585,"sku":"3108S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3108s","provider":"Iright","version":"1.0","type":"link"}
