出自BIOLOGICAL CHEMISTRY TAIWAN EDITION, Mary K. Campbell,英文p.711,中文803頁。 描述鈣離子為次級傳訊者的部分。 When the external trigger binds to its receptor on the cell membrane, it activates phospholipase C, which hydrolyzes PIP2 to inositol 1,4,5-triphosphate (IP3) and a diacylglycerol (DAG), in a process mediated by a different member of the family of G proteins. The IP3 is the actual second messenger.
白話翻就是,當外在刺激如賀爾蒙跟細胞膜受體結合時,會啟動磷脂酶C,磷脂酶C會水解 PIP2成為IP3及DAG。 IP3是真正的次級傳訊者... 查看完整內容 |
