GlossarySMAD7

inhibits TGF-β signaling to regulate cell growth and differentiation

SMAD7, also known as Mothers against decapentaplegic homolog 7, is a protein that plays a crucial role in regulating cellular processes by inhibiting the TGF-β (Transforming Growth Factor-beta) signaling pathway. This pathway is involved in cell growth, differentiation, and apoptosis. By acting as an antagonist, SMAD7 helps to control and fine-tune these cellular responses, which can be important in contexts such as tissue repair, immune response, and even cancer development.
