These data indicate that the SmSmad2 responds to the TGF - beta signals by interaction with receptor I , which phosphorylates it , whereupon it translocates into the nucleus presumably to regulate target gene transcription and consequently elicit a specific TGF - beta effect .
 GENE: SmSmad2; GENE: TGF - beta; GENE: receptor I; GENE: TGF - beta
