Gene Name
SMAD2, SMAD3
Protein Name
Smad2/3 (phospho Thr8)
Background
Thr8 of Smad2/3 locates at N-terminal MH1 domain and is not part of TGF-β-receptor-driven C-terminal activation motif. It is phosphorylated by kinases including MAPK and CDK. Thr8 phosphorylation modulates Smad2/3 nuclear export, DNA-binding capacity and protein stability, mediating crosstalk between TGF-β cascade and cell-cycle / MAPK pathways. It fine-tunes Smad-dependent transcription with context-dependent stimulatory or repressive outcomes.
