PI3K-Akt Signaling




Akt主要调节因子PI3K和PTEN的功能丧失可导致Akt过度活化。作为一个酶家族,PI3Ks可磷酸化PtdIns (Phosphatidylinositol,磷脂酰肌醇),生成3,4,5-三磷酸磷脂酰肌醇(PIP3)。当被受体酪氨酸激酶激活时,PI3K将PIP2磷酸化为PIP3,而后者随后可激活Akt信号传导。而通过将PIP3去磷酸化为PIP2,PTEN则充当着信号转导的负调控因子。



The serine-threonine protein kinase encoded by the AKT1 gene is catalytically inactive in serum-starved primary and immortalized fibroblasts. AKT1 and the related AKT2 are activated by platelet-derived growth factor. The activation is rapid and specific, and it is abrogated by mutations in the pleckstrin homology domain of AKT1. It was shown that the activation occurs through...   更多...
