真核起始因子2 - 维基百科,自由的百科全书
eIF2 (eukaryotic Initiation Factor 2,真核起始因子2)是一个重要的 真核起始因子,它的作用是在 真核翻译 起始过程中介导起始 tRNA (Met-tRNA i)与 核糖体 结合。 它是一个异源三聚体,由α、β、γ三个 亚基 组成。 eIF2也是第一个被发现的其蛋白 磷酸化 作用能够调控真核翻译的起始因子。 eIF2在真核翻译起始过程中扮演着关键角色。 它与 GTP 以及起始tRNA形成三聚体复合物(TC),在 eIF3 和 eIF5 的作用下,TC结合到40S核糖体亚基上共同形成43S前起始复合物 …

eIF2 调控 | Cell Signaling Technology
eIF2 起始复合体整合了各种各样应激相关的信号来调控全局和特异性 mRNA 翻译。 在适宜的条件下,eIF2 会结合 GTP 和 Met-tRNAi 形成三元复合体 (TC),三元复合体随后结合 40S 核糖体亚基、eIF1、eIF1A、eIF5 和 eIF3,形成 43S 起始前复合体 (PIC)。
Phosphorylation of the translation initiation factor eIF2
2015年1月15日 · At the molecular level, we demonstrate that eIF2 α P acts through an ATF4-independent mechanism to control Akt activity via the regulation of mTORC1. Specifically, eIF2 α P downregulates...

Phosphorylation of the eukaryotic initiation factor 2 (eIF2) α subunit is a well-documented mechanism to downregulate protein synthesis under a variety of stress conditions. eIF2 binds GTP and Met-tRNAi and transfers Met-tRNA to the 40S subunit to form the 43S preinitiation complex. eIF2 promotes a new round of translation initiation by ...
eIF2α信号通路相关研究进展 - 百度文库
目前发现了四种磷酸化eIF2α的丝氨酸琳氨酸蛋白激酶,分别是HRI,PERK,PKR及GCN2。 本文就该信号通路的研究进展进行总结分析。 eIF2α的磷酸化现象最早在兔网织红细胞中发现:血红素缺乏会激活一种eIF2α激酶导致eIF2α的磷酸化,从而控制细胞蛋白的合成。 这种被激活的激酶即血红素调节抑制因子HRI又叫HCI或HCR (Chen et al. 1991)。 接着又发现了能被dsRNA激活的eIF2a激酶PKR从酵母中也得到了一种eIF2a激酶GCN2 在氨基酸饥饿时被激活。 后来又发现 …
