Expression of smad induction
WebEctopic expression of Smurf, an antagonizer of Smad2, decreases Smad2 expression and blocks TGF-β induction of eNOS. Because Smad2 can interact with a variety of transcription factors, coactivators, and corepressors, Smad2 may thus act as an integrator of multiple signals in the regulation of eNOS expression. WebFeb 2, 2024 · SMAD3, a key transcription factor mediating TGF-β signaling, consists of an N-terminal MH1 domain that interacts with the Smad Binding Element (SBE), a linker region, and a C-terminal MH2 domain that interacts with other proteins . In canonical TGF-β signaling, TGFBR1 activation phosphorylates SMAD2 and SMAD3, enabling each to …
