AngiotensinIImediatedactivationofJNKPathwayviaPyk2dependent

Ang II binding to AT1-R triggers the activation of Ca2+ signaling and PKC. The signal is then transmitted to the Pyk2 and further to the small G protein Rac1 but not Cdc42, although the direct activation of Rac1 by Pyk2 is not proved in this study. In turn, Rac1 activates a small G protein-activated kinase whose identity is still controversial, but one of which has been suggested to be PAK1. Finally, the JNK cascade,......阅读全文
