SMADs are members of the MAD-related family of molecules. MAD-related proteins are a family of intracellular proteins that are essential components in the signaling pathways of the serine/threonine kinase receptors of the transforming growth factor beta superfamily. SMADs can be divided into receptor-regulated SMADs (R-SMADs: SMAD1, 2, 3. 5 and 8), common-mediator SMAD (co-SMAD: SMAD4), and inhibitory SMADs (I-SMADs: SMAD6 and 7). Briefly, activated type I receptors associate with specific R-Smads and phosphorylate them on a conserved SSXS motif at the carboxy-terminus of the proteins. The phosphorylated R-Smad dissociates from the receptor and forms a heteromeric complex with the co-Smad, Smad4, and together the complex moves to the nucleus. Once in the nucleus, Smads can target a variety of DNA binding proteins to regulate transcriptional responses.

Western blot analysis of SMAD7 in human HepG2 cells. The blot was probed with rabbit polyclonal SMAD7 antibody (SP4901) at 1:250.

This antibody was raised against amino acids 12-29 (RLWRSRAPGGEDEEEGAG) and 36-50 (ELRGEGATDSRAHGA) of human SMAD7. This sequence is 100% or highly conserved between human and multiple species.
