In a recent issue of Molecular Cell, Hong et al. (2008) describe an alternative mechanism by which mTOR promotes cell-cycle progression; it phosphorylates and activates SGK, which in turn phosphorylates the cell-cycle inhibitor p27, promoting its cytoplasmic retention.
在最近一期的《分子细胞》杂志上,洪等人(2008年)描述了一种mTOR促进细胞周期进程的替代机制;它磷酸化并激活SGK,而SGK反过来又磷酸化细胞周期抑制剂p27,促进其在细胞质中的滞留。
