摘 要:对氨基酸的精确感应是有效调控蛋白质或氨基酸合成与分解代谢及控制采食量的关键因素。雷帕霉素靶蛋白(mTOR) 和一般性调控阻遏蛋白激酶2(GCN2) 作为重要的信号转导分子,位于蛋白质合成与降解过程中整个信号通路的中心位点,是调控该过程的重要通路,并对蛋白质功能与作用的表达起到至关重要的作用。现主要围绕氨基酸信号对mTOR 和GCN2 通路的影响进行讨论,旨在阐述氨基酸信号如何在蛋白质合成和降解过程中发挥作用。

Abstract: Accurate amino acid sensing is a key factor for effectively regulating protein or amino acids synthesis and catabolism, and controlling food intake. Mammalian target of rapamycin (mTOR) and general control nonderepressible 2 kinase (GCN2) are located in the center of entire signaling pathway, which regulate the process of protein degradation and synthesis. Consequently, mTOR and GCN2 signaling pathway play a crucial role in protein synthesis and catabolism. Therefore, this review mainly focused on the effect of amino acid signal on mTOR and GCN2 pathway to further elucidate how amino acid signals are involved in protein synthesis and degradation.
