Biological Activity for SIS3
SIS3 is a selective Smad3 inhibitor; attenuates TGF-β1-dependent Smad3 phosphorylation and DNA binding. Has no effect on Smad2, p38 MAPK, ERK or PI 3-kinase signaling. Inhibits TGF-β1-induced myofibroblast differentiation of dermal fibroblasts. Also inhibits TGF-β2-induced endothelial cell differentiation in iPSCs.
