Mothers against decapentaplegic homolog 7 or SMAD7 is a protein that in humans is encoded by the SMAD7 gene.
SMAD7 is a protein that, as its name describes, is a homolog of the Drosophila gene: "Mothers against decapentaplegic". It belongs to the SMAD family of proteins, which belong to the TGFβ superfamily of ligands. Like many other TGFβ family members, SMAD7 is involved in cell signalling. It is a TGFβ type 1 receptor antagonist. It blocks TGFβ1 and activin associating with the receptor, blocking access to SMAD2. It is an inhibitory SMAD (I-SMAD) and is enhanced by SMURF2.
Smad7 enhances muscle differentiation.

Famous quotes containing the word mothers:
“Even today . . . experts, usually male, tell women how to be mothers and warn them that they should not have children if they have any intention of leaving their side in their early years. . . . Children don’t need parents’ full-time attendance or attention at any stage of their development. Many people will help take care of their needs, depending on who their parents are and how they chose to fulfill their roles.”
