A cDNA for a serine/threonine kinase receptor was isolated from a mouse brain cDNA library. The receptor transiently expressed on COS cells bound TGF-beta 1 not by itself but only when TGF-beta type II receptor was coexpressed. The molecular mass of the ligand-receptor complex was estimated to be 75 kDa. The type II receptor-dependent binding and the molecular mass of the complex suggest that the receptor is a TGF-beta type I receptor.
从小鼠脑cDNA文库中分离出一种丝氨酸/苏氨酸激酶受体的cDNA。该受体在COS细胞上瞬时表达,其本身并不结合转化生长因子-β1(TGF-β1),只有在共表达TGF-βⅡ型受体时才能结合。配体-受体复合物的分子量估计为75 kDa。Ⅱ型受体依赖性结合及复合物的分子量表明该受体是TGF-βⅠ型受体。
