Importance of eIF2α Phosphorylation and Stress Granule Assembly in Alphavirus Translation Regulation

Abstract excerpt

Alphavirus infection results in the shutoff of host protein synthesis in favor of viral translation. Here, we show that during Semliki Forest virus (SFV) infection, the translation inhibition is largely due to the activation of the cellular stress response via phosphorylation of eukaryotic translation initiation factor 2alpha subunit (eIF2alpha). Infection of mouse embryo fibroblasts (MEFs) expressing a...
