mTOR信号通路

发布时间:2024-06-26 09:21:00

哺乳动物雷帕霉素靶蛋白(mammalian target of rapamycin,mTOR)信号通路调节细胞的生长、代谢、增殖等过程,在细胞生长过程中扮演着重要的角色。在分化成熟的血管内皮细胞和心肌细胞中, mTOR在依赖于激活蛋白激酶B(Akt)引起的氧化应激条件下,调控细胞的凋亡和自噬过程。mTOR的这些功能通过增强血管再生和限制急性细胞死亡来促进心肌修复和组织再生。然而,在某些情况下,可以阻断mTOR信号通路来限制血管病变和促进微循环血流。

mTOR 是一种高度保守的丝氨酸 / 苏氨酸蛋白激酶,属于磷酸肌醇 3 激酶( phosphoinositide 3 kinase,PI3K)相关激酶,它主要通过两种不同的蛋白复合物mTORC1和mTORC2来完成其生理功能。其中mTORC1对mTOR抑制剂雷帕霉素敏感,而mTORC2不敏感。

mTORC1主要依赖Raptor来招募底物并与其结合,mTORC1的组成成分还包括富含脯氨酸的Akt底物(PRAS40)、Deptor、mLST8和mTOR等。mTORC1调控核糖体蛋白S6K1和真核细胞翻译起始因子eIF4E-BP1。PRAS40和Deptor在mTORC1激活时发生磷酸化并从复合体中脱离,能进一步激活mTORC1的活性;而mTORC1在活化后通过磷酸化S6K1和eIF4E-BP1来控制蛋白质合成及细胞的生长。

mTORC2的组成与mTORC1相似,主要包括mTOR,Rictor、mLST8、Deptor、哺乳动物应激激活的蛋白(mSINI)、与Rictor同时观察到的蛋白1(Pro-tor-1)。Rictor可以促进mTORC2的活性,但是对雷帕霉素不敏感。mTORC2可以调节细胞骨架肌动蛋白、细胞的大小、内皮细胞的存活与迁移以及细胞周期等生理过程,此外,还可以通过调控PKC、P-Rex1、P-Rex2、Rho GTPases以及Rho信号通路来控制细胞之间的联系。
