Smad2 (phospho Ser250)
Background
SMAD2 (Smad2) is TGF-β-pathway receptor-activated R-Smad. Ser250 locates within regulatory region of Smad2. Its phosphorylation occurs independent of canonical TGF-β-receptor-driven C-terminal activation motif and is catalyzed by diverse kinases. This modification fine-tunes TGF-β output by modulating Smad2 stability, nucleocytoplasmic shuttling and co-regulator interactions. It is functionally distinct from receptor-mediated activating phosphorylation at Ser465/467. Ser250 phosphorylation mediates pathway crosstalk integrating MAPK and other upstream cues.
