Application

Sugar insensitive 3 (SIS3) has been used as smad3 inhibitor in various cells.

Biochem/physiol Actions

Sugar insensitive 3 (SIS3) promotes drug-induced apoptosis and hinders the function of adenosine triphosphate (ATP)-binding cassette (ABC) transporter (ABCB1) and ABCG2. It resensitizes ABCB1 and ABCG2 overexpressed in cancerous cells, which contributes to chemotherapeutics.
SIS3 is a novel specific inhibitor of TGF-β1/ALK-5 phosphorylation of Smad3
