在许多生理和疾病过程中,TGF-β与Smads一起篡夺MAP激酶途径的分支以诱导细胞凋亡和上皮向间质转化,但TGF-β受体如何激活MAP激酶级联的详细机制尚不清楚。我们在此报道TRAF 6是JNK和p38的Smad非依赖性激活所必需的,其羧基TRAF同源结构域与TGF-β受体物理相互作用。TGF-β诱导TRAF 6的K63连接的泛素化,并促进TRAF 6和TAK 1之间的关联。我们的研究结果表明,TGF-β通过与白细胞介素-1 β/Toll样受体途径相似的机制激活JNK和p38。
In many physiological and disease processes, TGF-β usurps branches of MAP kinase pathways in conjunction to Smads to induce apoptosis and epithelial to mesenchymal transition, but the detailed mechanism of how a MAP kinase cascade is activated by TGF-β receptors is not clear. We report here that TRAF6 is specifically required for the Smad-independent activation of JNK and p38 and its carboxyl TRAF homology domain physically interacts with TGF-β receptors. TGF-β induces K63-linked ubiquitination of TRAF6, and promotes association between TRAF6 and TAK1. Our results indicate that TGF-β activates JNK and p38 through a mechanism similar to that operating in the interleukin-1β/Toll-like receptor pathway.
