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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp586N0721; DKFZp686J10186; hMAD-3; hSMAD3; HSPC193; HsT17436; JV15-2; LDS1C; LDS3; MAD homolog 3; mad homolog JV15-2; mad protein homolog; MAD, mothers against decapentaplegic homolog 3; Mad3; MADH3; MGC60396; Mothers against decapentaplegic homolog 3; Mothers against DPP homolog 3; SMA- and MAD-related protein 3; SMAD 3; SMAD family member 3; SMAD, mothers against DPP homolog 3; SMAD3\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M Mi","brand":"CST","offers":[{"title":"Default Title","offer_id":46800572874921,"sku":"12003V4","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-12003v4","provider":"Iright","version":"1.0","type":"link"}
