eIF3f是eIF3的亚基。我们之前表明eIF 3f被CDK 11 p46磷酸化,CDK 11 p46是细胞凋亡中的重要效应子。在这里,我们确定了第二个eIF3f磷酸化位点(Thr119)的CDK11p46在凋亡过程中。我们证明了eIF3f在体内被CDK11p46直接磷酸化。eIF3f的磷酸化在调节其翻译和凋亡功能中起重要作用。eIF3f的磷酸化增强了eIF3f在凋亡过程中与核心eIF3亚基的结合。我们的数据表明,eIF3f可能通过增加细胞凋亡过程中与eIF3复合物的结合来抑制翻译。
eIF3f is a subunit of eIF3. We previously showed that eIF3f is phosphorylated by CDK11p46 which is an important effector in apoptosis. Here, we identified a second eIF3f phosphorylation site (Thr119) by CDK11p46 during apoptosis. We demonstrated that eIF3f is directly phosphorylated by CDK11p46 in vivo. Phosphorylation of eIF3f plays an important role in regulating its function in translation and apoptosis. Phosphorylation of eIF3f enhances the association of eIF3f with the core eIF3 subunits during apoptosis. Our data suggested that eIF3f may inhibit translation by increasing the binding to the eIF3 complex during apoptosis.
