摘要
mTOR(the mammalian target of rapamycin)是一个进化上十分保守的蛋白激酶,属于PIKK(the phosphatidylinositol kinase-related kinase)超家族,作为Ser/Thr激酶而起作用。它可以汇聚和整合来自于营养、生长因子、能量和环境压力对细胞的刺激信号,进而通过下游效应器(4EBP1和S6Ks)调节细胞生长。mTOR信号通路还影响胚胎干细胞和早期胚胎的发育,并且与肿瘤、肥胖及代谢紊乱等疾病有关。对mTOR信号通路的生理功能、分子组成和调节机制的研究不仅可以深入了解细胞生长调控的机制,而且对于相关疾病的治疗具有重要意义。
